ReplyDeleteThe human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages. The first stage is the cephalic phase of digestion which begins with gastric secretions in response to the sight and smell of food. This stage includes the mechanical breakdown of food by chewing, and the chemical breakdown by digestive enzymes, that takes place in the mouth.
ReplyDeleteSaliva contains digestive enzymes called amylase, and lingual lipase, secreted by the salivary glands and serous glands on the tongue. The enzymes start to break down the food in the mouth. Chewing, in which the food is mixed with saliva, begins the mechanical process of digestion. This produces a bolus which can be swallowed down the esophagus to enter the stomach. In the stomach the gastric phase of digestion takes place. The food is further broken down by mixing with gastric acid until it passes into the duodenum, in the third intestinal phase of digestion, where it is mixed with a number of enzymes produced by the pancreas. Digestion is helped by the chewing of food carried out by the muscles of mastication, the tongue, and the teeth, and also by the contractions of peristalsis, and segmentation. Gastric acid, and the production of mucus in the stomach, are essential for the continuation of digestion.
Peristalsis is the rhythmic contraction of muscles that begins in the esophagus and continues along the wall of the stomach and the rest of the gastrointestinal tract. This initially results in the production of chyme which when fully broken down in the small intestine is absorbed as chyle into the lymphatic system. Most of the digestion of food takes place in the small intestine. Water and some minerals are reabsorbed back into the blood in the colon of the large intestine. The waste products of digestion (feces) are defecated from the anus via the rectum.
My reflection-
ReplyDeleteAfter doing this unit i learn’t the functions for the digestive system:
The teeth-are a group of hard organs found in the oral cavity. We use teeth to masticate (or chew) food into tiny pieces. They also provide shape to the mouth and face and are important components in producing speech.
The tongue-is anchored to the floor of the mouth and slung at the rear from muscles attached to a spiky outgrowth at the base of the skull. It is a strong muscle that is covered by the lingual membrane and has special areas that detect the flavor of food. The tongue is made up of muscles covered by mucous membranes.
The esophagus-is a long, thin, and muscular tube that connects the pharynx (throat) to the stomach. It forms an important piece of the gastrointestinal tract and functions as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach.
The stomach is the main food storage tank of the body. If it were not for the stomach’s storage capacity, we would have to eat constantly instead of just a few times each day. The stomach also secretes a mixture of acid, mucus, and digestive enzymes that helps to digest.
The gallbladder is a small storage organ located inferior and posterior to the liver. Though small in size, the gallbladder plays an important role in our digestion of food. The gallbladder holds bile produced in the liver until it is needed for digesting fatty foods in the duodenum of the small intestine. Bile in the gallbladder may crystallize and form gallstones, which can become painful and potentially life threatening.
The pancreas-is a glandular organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland. Functioning as an exocrine gland, the pancreas secretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food. Functioning as an endocrine gland, the pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day. Both of these diverse functions are vital to the body’s survival.
The small intestine-is a long, highly convoluted tube in the digestive system that absorbs about 90% of the nutrients from the food we eat. It is given the name “small intestine” because it is only 1 inch in diameter, making it less than half the diameter of the large intestine. The small intestine is, however, about twice the length of the large intestine and usually measures about 10 feet in length.
The large intestine is the final section of the gastrointestinal tract that performs the vital task of absorbing water and vitamins while converting digested food into feces. Although shorter than the small intestine in length, the large intestine is considerably thicker in diameter, thus giving it its name. The large intestine is about 5 feet (1.5 m) in length and 2.5 inches (6-7 cm) in diameter in the living body, but becomes much larger postmortem as the smooth muscle tissue of the intestinal wall relaxes.
Extending from the inferior end of the large intestine’s cecum, the human appendix is a narrow pouch of tissue whose resemblance to a worm inspired its alternate name, vermiform (worm-like) appendix. It is located in the right iliac region of the abdomen (in the lower right-hand abdominal area), measuring about four inches long and roughly a quarter of an inch in diameter.
The rectum is the final segment of the large intestine that connects the colon to the anus. It stores fecal matter produced in the colon until the body is ready to eliminate the waste through the process of defecation.
The anus, or anal canal, is the final segment of the gastrointestinal tract. It acts as the orifice that feces pass through during defecation.
Thats what i learn’t i really enjoyed learning about the digestive system,i am very privileged to learn this,i am soo proud that i learn’t how the food i eat travels thru the digestive system it has been a great oppotunity.
Thank you mr prakarsh for teaching us about the digestive system.
This is what I learnt this unit.
ReplyDeleteStarting from the top of the digestive system, we have the mouth. The mouth holds three important parts of the digestive system. First we have our tongue. Our tongue is responsible for giving taste to your food. The mouth is able to identify sweet, salty, bitter and sour. Second is the teeth. Teeth are responsible for grinding food down into smaller pieces so we are able to swallow it. The three types of teeth are named; Incisors, Canines, Premolars and Molars. Incisors are used to cut/ chew into food. A Canine's function is to tear into food such as; meat. A Premolars function is to crush down food. Molars are used to grind down food. The last function of the mouth is salivary glands. Salivary glands are used to cover the food in which is being digested in liquid to soften it down to swallow. After food has passed the mouth area, it travels to the esophagus to be transported to the stomach. The stomach's purpose is to break down food with enzymes. The acid which is in the stomach is called bile is produced in the liver and the pancreas holds it until it's ready to pass to the stomach. After the food has passed the stomach travels to the small intestine. The small intestines function is to absorb the nutrients and minerals from food. The large intestine is responsible for absorbing water. The food is passed to the anus which is where the food which has been digested is stored before it is passed out of the anus to be evacuated.
We learnt what the different food groups are; Dairy, Vegetables, Fruits, Grains, and Protein. We need all of which to sustain a healthy body. We also learnt the difference between Carnivores, Herbivores, and Omnivores. Carnivores are only able to eat other animals, Herbivores are only able to eat plant based foods, and Omnivores can do both. I learnt which animals belong to the different diets.
Thank you Mr. Prakash for teaching me ‘food and digestion’ in this unit.

ReplyDeleteKia ora this is Deejah george
ReplyDeletei have learnt a lot about the digestive system the five names of food groups, the mouth, esophagus, stomach, small intestine, and the large intestine and do you know when you eat some food it can stay in your stomach or in you for like six to eight hours for food to pass through to the five food groups, now i'm gonna talk about the carnivores teeth and so much more don't here is information about carnivores.
Ko te nuinga o nga kaimoana he roa, he koi nga niho e uru ana ki te haehae, te haea, te tarai ranei i nga kiko. Ahakoa he maha ano nga kaataata kei muri i o ratou waha, me nga kurupae koi i mua, ko nga niho whakahirahira mo nga kaikuku tetahi koikoi roa, koi koi.

ReplyDeleteMy reflection- After learning about the digestive system I know the different types of parts included in the digestive process. We have the mouth, salivary glands, esophagus, liver, stomach, gallbladder, pancreas, large intestine, small intestine, appendix, rectum and anus. The digestive process starts before the food even hits our mouths. When the food is in your mouth your teeth chew and rip at the food so that it's smaller and easier to swallow and go through the esophagus. Then the food travels through to your stomach then to the small intestine hits the rectum and comes out of your anus. Mouth, the mouth is where the food gets moistened. In the stomach is where the food gets broken down by all the chemicals and bounces of the walls in our body to help break down foods. After this it travels to the other areas and after a while it comes out your anus.The different types of teeth are incisors, Canines, Premolars, canines and Molars. Enzymes are a vital part of the digestive system; they break down proteins and starches. Enzymes speed up the digestive process. There are five different food groups; these are carbohydrates, protein dairy products, fruit vegetables Fats and sugars. In a chemical test you need a food type, example, substance used to test, colour at start, colour if food is present and does it need heat. Food= protein, Example= egg, Stance used to test=Biuret reagent (NaOH) (II), Colour at start=blue, Colour if food is present=mauve and Does it need heat=no. Humans and animals need food so they can have nutrients and energy to be productive during the day. Carnivores are animals that only eat meat, Herbivores animals that only eat plants and omnivores are animals that eat both meat and plants. Carnivores herbivores and omnivores have different types of teeth and mouth shape depending on what they eat. This unit made me aware of so many things that I didn't know before.

ReplyDeleteThroughout a bit of term 2 and this term I have learnt about the digestive system.i have learnt about types of food groups (protein,calcium,carbohydrates,etc.) and why it is important to keep a nice and healthy body. I've Also learnt about the different types of teeth between herbivores cannibals and omnivores and also what type of food and nutrients they eat.But the most important part of this learning term i have learnt and studied about was the digestive system.The digestive system is a process our bodies go through when we eat food.There are 16 (17 if you add the appendix) parts to the digestive system and here are them stated in order form.
ReplyDeleteMouth,Salivary glands,Teeth,Tongue,Oesophagus,Stomach,Liver,Gallbladder,Pancreas,Small intestine,Appendix,caesium,Large intestine,Rectum,Anus
ReplyDeleteHere is a word form of how the digestive system works.:)
The digestive system works in this order form.The first part of digestion start at the mouth that is where food is first present from there the salivary glands come into role by producing saliva to help moisten food easy for swallowing.Once the food has been present that's where the teeth come into contact with the digestive system.The teeth job is to chew and grind the food down with its three types of teeth (incisors.canines,molars) until its broken into chunks ready for the next stage.During this process of digestion there is a enzyme (the amalayes) which is released during eating and chewing the food and breaks down scratches.Once the food has been present and first part of digestion is done the tongue then comes into role.The tongues job is to move the food around in the mouth while being chewed and once done the tongue pushes the food back down the throat opening the oesophagus.From there the oesophagus (a long muscular tube that leads down to your stomach) transfers your food to the stomach where the next part of digestion can begin.Once the food has reached the stomach the stomach then begins to break the food down using its stomach acid and a type of enzyme (Pepsin) which digest the protein in our food.After 3 hrs in the stomach the food then travels through to the small intestine,while the foo is being transferred to the small intestine the liver and gallbladder come into play.The liver's job is to create bile duct (a yellowish green liquid that digested fats) and transfers it into the gallbladder which is then secretes it into the duodenum (the start of the small intestine).from there the pancreas then begin its process.The pancreas job is to make pancreatic juices and enzymes (lipase) that break the fat molecules down into fatty acids and glycerol for easier absorption into the body,they also help your digestive system by making hormones.From there the food then enters the small intestine.the small intestine is the important part of digestion,the small intestines job is to absorb all the nutrients inside the walls of the small intestine.There are millions of these little finger like things called villi,the villi are what absorb the nutrients and takes them to the bloodstream then through to your hole body.once all the nutrients has been collected the food and the waste is then transferred to the large intestine.At the start of the large intestine there is the appendix there is no function of this part but still plays a role in the digestive system.There is also the calcium as well.The cecum job is To absorb fluids and salt and any remaining water that remain after intestinal digestion and then it goes through the large intestine where all fluids are still absorbed and then all left over waste form into a stool,then transferred to the rectum.The rectum is a 8 inch long chamber that connects the large intestine to the anus.The rectums job is to receive the stool from the large intestine and let the body know when it is time to go to the bathroom.And the last part of digestion is the anus.The anus Job is to to take all the leftover food and waste from the body out and through the exit section.
Throughout this topic i have been able to learn and discover new things about ourselves.I have went in with nothing but had come out with much more than i should have.i really enjoyed this study on digestive system and would like to look forward to new things in science.I would also like to give a big thanks to !!UNCLE!! Prakash for teaching me and for educating me on this term of digestion in a very comprehensive way but for mostly getting me to where i am today in requirements of science.I really hope we can carry on with new discoveries and new things to learn.But other than that Ka pai and Boyeeee. :)

DeleteName the parts of the human digestion system including each type of tooth. Incisor, molars, premolar, canine. Tongue, salivary glands, esophagus, stomach, gallbladder, pancreas, liver, small intestine, large intestine, rectum, anus
ReplyDeleteDescribe the steps of the digestion process from ingestion to excretion. The digestive system starts even before you take a bite, when you look at your food your salivary glands start producing saliva containing enzymes and 98% water. When eating food your tongue helps break down food by moving it around in your mouth turning it into bolus a mushy paste that goes down a 8 inch long muscular tube that connects the mouth to the stomach. Now that the food enters the stomach, the stomach walls pound the bolus that breaks it into pieces then the hormones secreted by cells in the lining triggers enzymes and saliva rich juices that dissolve the proteins in the bolus has to wait about six to eight hours before reaching the small intestine but it has to the end
I have learnt a lot about the digestive system. About all the different types of teeth. The names of the digestive system starting with the mouth and the teeth. The teeth will break down the food and the tough will help it go through the Oesophagus to the stomach. The food can stay in your stomach for 6-8 hours or 38 minutes. Then the food will go to the pancreas to get all the sugars and fats apart from each other. The liver is next for the digestive system. The liver is an organ about the size of a football. It sits just under the rib cage on the right side of the abdomen. Next is the gallbladder, a small pouch that sits just under the liver. Small intestine is an organ in the gastrointestinal tract where most of the end absorption of nutrients and minerals from food takes place. The major function of the Large intestine is the recovery of water. Rectum helps the food go to the anus.
ReplyDeleteThanks mr Prakash for what I have learnt from u about the digestive system.
I learnt about different parts of the digestive system and i learnt about the different functions of them and how they help the body and whats useful and whats not useful but for the tooth i didn't pay much attention to it The digestive starts at the mouth where the food enters and then it passes down the opheges after the teeth have chewed it and it starts to digest with different types of series and steps special enzymes playing important roles in digesting carbohydrates, proteins, and lipidsIt starts at the mouth Salivary glands,helps food get broken down while being chewed Esophagus Propels food to the Stomach Mouth Stomach breaks down food and turns it into chyme Liver,filters blood iGallbladder: to store and concentration bile a yellow and brown digestive enzyme. small intestine: to break down nutrients and puts it in the blood systemLarge intestine: absorbing water and electrolytes producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination Appendix no function Rectum Lets you know when it is time to go toilet Anus the last part of the digestive system Enzymes create chemical reactions in the body. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.Carbohydrates. Carbohydrates give you energy, calcium and B vitamins. ... Protein Dairy products Fruit and vegetables Fats and sugarsTake small quantity of the food items to be tested.To help your body work and it gives you energy throughout the day.The three diets of animals include creatures that eat only plants, those that eat only meat, and animals that eat both plants and meat. Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores.
ReplyDeleteMy reflection-Kia ora, my name is Honekai. I learnt a lot about the digestive system with Mr.Prakash, I learnt the organs and how they work. I learnt about how our taste buds have a variety of different taste sensations and how the body functions. Here is an example of the digestive system parts esophagus, stomach large intestines gallbladder pancreas small intestines pharynx liver salivary Retum The mouth is the beginning of the digestive tract. In fact digestion starts here as soon as you take the first bite of a meal.What is the function of the digestive system? Read about the human digestive system and its functions and organs.Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

ReplyDeleteDigestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

My reflection- kia ora mr Prakash as i was sick for most of the lesson when you were teaching food and digestion I missed heaps how ever i did appreciate the work you put on hapara workspace. When I did come back I knew some of the parts in the digestive system, I’m still gonna catch up but in a later day, I did like listening to everyone's presentation.
ReplyDeleteKia Ora Mr Prakash, learning about all of this human digestive system stuff has been very interesting. Getting to learn the names was very interesting such as; Pharynx, Liver, Gallbladder, Small intestine, Large intestine, Salivary glands, Mouth, Esophagus, Stomach, Pancreas, Appendix, Rectum and Anus. The digestion process starts in the mouth, then leads to the esophagus to stomach, to small intestine, to large intestine, then travels into the rectum and then crap ends up coming out of the anus. At the start food is processed and pushed through to the esophagus and into the stomach which then means a series of contractions called peristalsis. Before the opening into the stomach, is an important ring-shaped muscle, named the lower esophageal sphincter. The sphincter opens up to let the food draw into the stomach and closes up so it can store in there. Digestive enzymes speed up the process of chemical reactions that break down the large food molecules into small molecules. The enzymes in your body help perform very important tasks ; these then include building muscle, destroying toxins, as well as breaking down food particles during digestion. The five food groups are Carbohydrates, Protein, Dairy Products,Fruit and Vegetables, and Fats and Sugars. By describing a test you're gonna wanna take a small quantity of the food required to be tested, then put in about 2-3 drops of iodine solution, then observe it and watch it dissolve, and with starch the colour will end up coming out like a Bluey-black. Each of the food groups are needed because they each provide a range of nutrients and all have a part with helping the body function. For example, vegetables, legumes and fruit protect against illness and are essential to a healthy diet. Animals that eat plants exclusively are herbivores, and animals that only eat meat are carnivores. When animals eat both plants and meat, they are called omnivores.

ReplyDeleteHey Mr Prakash, After studying this unit I learnt the different types of digestion organs, What connects the mouth to the stomach (oesophagus), All the juices and enzymes that break down different food types which then leads to the anus. The first step to digestion is the mouth, The mouth holds the food in place which allows the salivary glands and teeth to break down the food particles into smaller easier to swallow parts. After that function the food is then squeezed by the oesophagus walls which the particles travel towards the stomach, The stomach has many juices and enzymes that help break down the food it also releases Hydrocholic acid that also helps break down foods. The small and large intestine absorb juices from the stomach and after those processes the food is at its last organ the anus, The anus is where the food comes out and into the toilet.
ReplyDeleteThese are most of the main organs and each one has different functions, Here are the other digestive organs. Pancreas - Creates natural juices called pancreatic enzymes to break down foods. Liver - The liver is known to cleanse your blood and release a digestive liquid called bile. Bile duct - The bile duct connects the liver to the small intestine, Its main job is to carry the bile fluid to the Gallbladder - The gallbladder stores bile a combination of fluids,fats and carbohydrates, Bile helps break down fat from your intestine. Small intestine - The small intestine absorbs nutrients and minerals which then gets emptied into the large intestine. Appendix - This digestive organ is known to be a left over organ which acts as a storehouse for good bateria it also reboots after diarrhea. Rectum - The retum connects the colon to the auns. Anus - This is the final part of the digestive system which crap is transferred to the toilet bowl.
Enzymes help speed up the chemical reactions that are in your blood cells, There are different enzymes which break down different food particles (Lipase, Breaks down fats/oils, Protease, Break down proteins and Amylase which breaks down carbohydrates).
The main food groups are Fruits,vegetables,proteins,carbohydrates and dairy, Each food group provides different nutrients. Identify the different food groups, Glucose - substance used to text glucose is benedicts it will start as a blue colour and the colour will change orange if the food is present you don't need heat for testing glucose either. Starch - iodine is tested for starch. Its colour at the start will begin as yellow/orange and if starch is present in the food it should turn a smokey balck color. Protein - Protein is tested with copper sulfate the color will begin as blue and if present pink/purple. Oil - Tested with paper and if food is present it should be clear/transparent. Each food group contains different nutrients. It is important to eat a variety of foods within each five groups.From eating the same exact foods can cause stomach problems from not being able to receive different nutrients.
Carnivores,Omnivores and Herbivores - Carnivores have small powerful jaws and have a diet of only meat, Omnivores have small jaws which help chew food they too eat meat and vegetables and Herbivores have a large jaw and only eat plants. Carnivores have sharp canines and incisors at the front of their jaws and small molars at the back, Canines are used to rip,tear and cut prey. Herbivores have small incisors and premolars and molars at the back of their jaws that grind plant materials. There's a little gap between the incisors and molars that helps move the food around. Well, omnivores have a similar jaw to carnivores; they eat both meat and vegetables so they have small canines and incisors at the front and molars at the back.
That concludes my reflection I really enjoyed this unit and would like to know more and more information about different organs etc. I found it easy remembering the digestive organ functions and can’t wait for more units to come this term thank you!
Kia ora Mr Prakash, after we learnt about the digestive system I was able to name every digestive organ in the digestive system. Starting from the top of the digestive system, mouth, teeth ( incisors, canines, premolars and molars)the teeth help grind, tear and rip food apart so it’s easy to digest, tongue, salivary glands, oesophagus, stomach, liver,gallbladder, bile duct, small intestine, large intestine, appendix, rectum and the anus. The steps of the digestive system, first the food enters your mouth where the salivary glands shoots out salivar as you use your teeth to chew the food, the tongue pushes the food to the oesophagus, the oesophagus slowly pushes the food to the stomach, mixing and breakdown of food by contraction and relaxation happens in the stomach, the function of the liver is ot filters blood and produces bile or bile duct, the gallbladder is to store and concentrate bile, the function of the small intestine is to absorb the nutrients from the food, there is no function for the appendix, the function of the large intestine is to absorb waters and vitamins from the food, the function of the rectum is to store stool from the colon, the function of the anus is to release the leftover food. Enzymes are important because it helps you have a healthy digestion and a healthy body. The 5 food groups are carbohydrates, protein, dairy products, fruit and vegetables and fats and sugars. A chemical test for starch is to add iodine solution( it should turn yellow and brown). Chemical test for glucose is to add benedict’s solution(it is a clear blue solution). Chemical test for protein is to add biuret solution( it turns blue) chemical test for lipid is to add ethanol. Each food group is important to the human body because it gives us energy, keeps us warm and it helps with growth and repair. A carnivore is an animal or living being that only eats meat and nothing else. A herbivore is an animal or living being that only eats vegetables and greens. An omnivore is an animal or living being that eats everything like meat and vegetables.

ReplyDeleteKia ora Mr Prakash I learnt a lot about the digestive system this term and how all of the parts function. The parts of the digestive system areLarge intestine, Small intestine, Caecum, Pancreas, Liver, Stomach, Gallbladder, Esophagus, Appendix, rectum, salivary glands, anus. There are four different types of teeth the incisors are located at the front of your mouth also known as canines they help cut food. Premolars are located just behind your incisors to help grind and chew food to make it easier to digest food.
ReplyDeleteThe mouth is the very beginning of the digestive system, and it is responsible for breaking down food so that it can travel safely down the rest of the digestive tract.
The rectums work is to get stool from the colon, at that point the stool is Pooped out from the anus.
Before starting this unit I knew very little but now i know a lot.
MEAN MAORI MEAN (its only a little bit but something is better than nothing yah fell me cuh) UwU
DeleteKia ora Mr Prakash, Learning all about the human digestive system has been fun and very interesting. Getting the opportunity to learn what Pancreas, Esophagus, Small intestines, Large intestines, Appendix, Bile Duct, Liver, Stomach, Anus, Gallbladder, Salivary glands, Mouth, Pharynx do including Molar, Incisors, Canine, Premolars has been extremely helpful and interesting now knowing what my body parts do, etc. The food starts at the mouth and leads down to the esophagus then into the stomach travels into the small intestines and then into the colon also known as large intestines then into the rectum then out the anus. Mouth: When food hits your mouth the types of teeth tear and break down foods. Salivary Glands: Helps the food get moist so that it's easier for the molar, incisors, canine, premolars to chew the foods. Pharynx: Receives foods to be shipped down to your esophagus. Esophagus: Transports food materials to the stomach. Stomach: It holds food while the stomach enzymes mix with the food. Small intestines: Absorbs the nutrition and minerals from the food getting transported to the large intestines. Large intestines: Absorbs the water and salt from the food slowly travelling to the rectum. Rectum: Where your food gets stored to be pushed out. Anus: Where the food comes out of. Enzymes are extremely important because they collaborate with a lot of chemicals that are in your body. Fruit and vegetables, Carbohydrates , Dairy, Protein, Fat. So for starch to test it you use iodine solution, for glucose you test benedict's reagent , for protein you test biuret reagent, fo fat you test paper.Each food group is very well needed and important for the human body because of the amount of warmth, growth and repair your body has to maintain everyday. Carnivore: Feeds on other animals. Herbivore: Feeds on plants. Omnivore: Animal/Person that feeds on a variety of plants and animals. Carnivores have small effective jaws and have a diet of only eating meat, Omnivores have small jaws which help chew food, they consume meat and vegetables and Herbivores have a big jaw and consume plant life. Carnivores have sharp canines and incisors on the front of their jaws and small molars at the returned, canines are used to rip,tear and reduce prey. Herbivores have small incisors and premolars and molars at the back of their jaws that grind plant materials. there's a bit of a gap among the incisors and molars that helps move the meals round. Omnivores have a similar jaw to carnivores; they consume each meat and greens in order that they have small canines and incisors on the front and molars on the back. I’ve come to the conclusion of my blog reflection. I've enjoyed learning so much about this unit of this subject and can’t wait to learn much more.
ReplyDeleteI Really enjoyed the digestive system because it was just so much fun to learn about the body or your insides because then when you eat you get a better understanding about how it's going to go.
ReplyDeleteMy reflection- I highly think that I was successful at knowing what and how the digestive system works. I think i need a little bit more work on naming each type of tooth in the mouth because I need to read the book properly so I can tell you that I know how to name those teeth in the mouth. I think that I was very successful in Describing the steps of the ingestion of the digestive system and the excretion of the digestive system Starting from the mouth . (The mouth) is the very beginning of the digestive system, and it is responsible for breaking down food so that it can travel safely down the rest of the digestive tract. (The tongue) is an important part of the digestive system, and is important for chewing, swallowing and tasting food. (The esophagus) is important for transporting food to the stomach, the esophagus muscles are so strong that you can eat upside down. (The large intestine) is a 1.5 meter long organ that is a part of the digestive system. The large intestine has three primary functions. 1 absorbing water and electrolytes-2 producing and absorbing vitamins-3 forming and propelling feces toward the rectum for elimination.(The small intestine) does most of the work in the digestive system, it absorbs most the nutrients you get from your food into your bloodstream. (gallbladder) is a fruit shaped organ just below the liver. Its primary function is storing concentrate bile. It's a yellowy brown-ish enzyme manufactured by the liver. (The pancreas) is located in the abdomen, It converts food into fuel for the body cells, the pancreas has two main functions 1 an exocrine function that helps in digestion and endocrine function that regulates blood sugar. (The rectums) work is to get stool from the colon, at that point the stool is excreted out from the (anus) . And that's the end of the steps of the digestive system. Enzymes make compound responses in the body. They really accelerate the pace of a synthetic response to help bolster life. The compounds in your body help to perform significant errands. These incorporate structured muscle, crushing poisons, and separating food particles during processing.
Carbohydrates
Carbohydrates give you energy, calcium and B vitamins. These could be servings of pasta, rice, oats, potatoes and sweet potatoes or noodles, yam, couscous, bread, barley and rye. Breakfast cereals are also a carbohydrate and many contain extra iron too.
Protein
Think of proteins as building blocks for the body – they help it grow and repair itself. Protein is found in meat, fish and eggs, while nuts, beans, lentils, peas, dahl, Quorn and soya are great vegetable proteins. These foods also provide us with iron and other vitamins and minerals.
Dairy products
Packed with calcium, protein and vitamins such as vitamins A, D and B12, dairy products keep our bones and teeth healthy. Our bodies easily absorb the calcium from these foods, such as milk, yoghurt, fromage frais and cheese.
Fruit and vegetables
Fruit and veg – fresh, frozen, tinned, dried and juices – are brilliant for our diets. They’re full of health-giving vitamins, antioxidants and fibre – that keep us feeling full and our digestive systems healthy – plus they’re low in calories. By eating a wide variety of fruit and veg, you’ll be getting a range of the important nutrients they contain.
Fats and sugars
It’s important not to have too many foods from this group as they give us a lot of energy from calories but not much nutrition. Try to keep foods such as butter, margarine, cooking oils and salad dressings to a minimum and save chocolate, crisps, sugary soft drinks, sweets, jam, cream, cakes, pudding, biscuits and pastries for the occasional treat.
The carnivores eat lots of meat and herbivores eat vegetables and omnivores are just like humans because they eat both carnivores and herbivores.

DeleteKa pai Xavier, kia kaha. I really enjoyed the bits you put in your own words.
DeleteKia Ora Mr Prakarsh, The Food and Digestive System Unit was a bit of a challenge for me. Mainly memorising is a strong suit for me, but the digestive system was just not on my side. Some things that I have learnt from this unit are the different parts of the digestive system. Due to not wanting you to sit here reading this comment, I will just mention some of the parts that I’m very familiar with. Teeth - are used to be able to grind on the food and make it mushy. The Salivary Gland - produces Saliva in the mouth so that the pile of food has a smooth travel throughout the digestive system. The Esophagus - a long tube that starts at the mouth and ends at the stomach, it’s like a hallway from the first block to the next. Stomach - the stomach is another area or part that helps break up the food with a liquid acid and its walls. These are the few starting parts of the digestive system. Another unit we covered was Herbivores, Carnivores, Omnivores, and the difference between them. The difference is Herbivores are the type of living creature that only eat herbs and plants. Carnivores are the opposite kind of and can only eat meat. Omnivore is the creature or living thing that can eat both plants and meat. Examples for each can be…
ReplyDeleteHerbivore - Giraffe, Sheep, Goat, and Rhino
Carnivore - Dog, Lion, Sharks, and Cheetah
Omnivore - Humans, Bears, Racoon, and Squirrels.
All of the things I have mentioned above are the things I’ve learnt in the units of Then DIgestive System, and Herbivores, Carnivores, and Omnivores. Lets hope the next unit is a bit easier for me :) Byeee.

DeleteKia ora mr Prakash in this term i have learn about the digestive system.There are 16 parts to the digestive system.The mouth,teeth,salivary glands,oesophagus,stomach,liver,gallbladder,pancreas,small intestine,appendix,large intestine,rectum,anus.i have learnt the function of them and where they're located.I have learnt about the different types of food group which are the (carbohydrates,calcium,veggies & fruits etc.)and i have learnt about the different types of teeth between the cannibal herbivore and the omnivore and what foods they eat and why they eat and what they need to keep alive.I enjoyed this term of digestive system and i like to learn more about it in the coming future.

DeleteKia Ora Mr Prakash,
ReplyDeleteIn this unit of Digestive System, I have learnt 15 different types of digestion parts.
Let's start with The teeth your tongue and the mouth, The mouth is the entry point for food, but the digestive system often gets ready before the first piece of food even enters our mouth, the tongue helps with pushing the food around your mouth while your teeth chew the food.When you're wanting to swallow the tongue pushes some mushed up food towards the back of your throat and into the opening of your esophagus. Esophagus, an esophagus is a tube leading from the throat to your stomach.Liver, the liver processes nutrients absorbed from the small intestine, the small intestine, breaks down food from the stomach and absorbs much of the nutrients from the food.Stomach, the stomach holds your food while it’s being mixed with enzymes the enzymes help to break down food into a usable form. Gallbladder, the gallbladder helps to store and concentrate bile from the liver. Pancreas, the pancreas converts food we eat into fuel for the body cells. Appendix, the appendix has no function at all. The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist. It also helps break down carbohydrates. Rectum, the rectum's job is to receive stool from the colon, it can tell you when you need a kaka and it'll hold the kaka until it’s able to evacuate. The anus is the part where the kaka comes out. Its physiological role is to carry bile from the gallbladder and empty it into the upper part of the small intestine.Pharynx, The pharynx (throat) is involved in both digestion and respiration. It receives food and air from the mouth, and air from the nasal cavities.Epiglottis, The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
I can now be confident in the different types of digestive systems and their functions! Thank you Mr Prakash for teaching us, 9T about the digestive system it was really helpful and I think i’ll always remember it. Byeeee!
Kia Ora T'shaan, I'm so proud of you :)
DeleteE wehi ana te kite ngā whakaaro nui kei a koutou 9T. Rangatira ngā mahi!!
ReplyDeleteThe digestive system starts off before you even take a bite, the salivary glands activate and starts to produce saliva containing enzymes and 98% water. When eating food your tongue helps to break down food by moving it around. The oesophagus is a long tube that connects your mouth to your stomach. When the food that’s being digested enters the stomach, the stomach walls start to pound the bolus that breaks it into pieces, then the hormones that are secreted by cells in the lining triggers enzymes and saliva rich juices that start to dissolve the proteins in the bolus. Carrying on from the stomach the bolus continues towards is the Gallbladder, Liver, and the Pancreas and the Liver and the Gallbladder hold bile which helps the food that is being digested then we go down to the small intestine which is covered in millions of tiny projections called vili, the vili creates a surface area the maximize molecule absorption. The remaining fibre, water and dead cells sloughed off during the digestion of the food are heading it’s way to the large intestine also known as the colon. The body drains the remaining fluid from the walls of the intestines, what will be left is a mass called stool which afterwards goes through the large intestine and ends up in a pouch called the rectum, the rectum tells the body when it’s time to expel the waste. The stool exits through the anus. That’ll be the end of the 30-40 hour process of the digestive system thanks Mr Prakash for teaching me this :D.
ReplyDeleteBubye :)
This looks so interesting! Varren, your explanation and description of the process is so clear and informative. Well done!
