The Incredible System in Our Body, the Digestive System



The digestive system is a system which breaks down large insoluble molecules into smaller soluble molecules which can pass through the wall of the gut into blood. This system includes a keyword; “digestion”. Everything in the digestive system is all about digesting the food we eat. This way, we don’t end up choking, every time we eat something. This process turns food, into small chunks and into nutrients.

This system starts from the mouth. When we chew something with our teeth, it makes the food have a larger surface are. Then, our saliva starts changing the carbohydrates into sugar. Carbohydrates are substances such as sugar or starch that consists of carbon, hydrogen, and oxygen. It provides the body with energy and heat.

The food is then pushed down the esophagus, to the stomach by the peristalsis. Peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When the muscle relaxes, the food drops down and when it contracts at the top, the food at the bottom is pushed down. Then, the food will go to the stomach. Here, the food will get churned around by more waves of peristalsis to make it into mush, and it mixes with one kind of acid, called “gastric juice”. This contains “enzyme” which breaks down proteins, it also contains “hydrochloric acid”, which kills bacteria.

The food is then released, a little bit at a time, into the first part of the small intestine. Intestines are long tubes in the body, between the stomach and the anus. There is one type of digestive juice called “bile”, and it helps the small intestine work more effectively. It is made by the liver and stored in the bag called “gall bladder”. The gall bladder neutralizes the acid that was added in the stomach. The bile also helps emulsify the fats, which means to make the fats into smaller blobs to make their surface area larger. The food is now a semi-liquid like a smoothie. It passes to the 2nd part of the small intestine. The intestines allow rapid diffusion of the products of digestion. There are walls called “villi walls” in our body, which are only one cell thick, and helps speed up the diffusion. Each villi has a blood vessel and a lymph vessel to carry food away. The food which cannot be digested will end up in the large intestine. It enters to the colon where most of the water is reabsorbed into the blood.

The indigestible remains form semi-solid faeces, which is stored in the rectum, which is eventually passed out the anus. The anus is the opening in a person’s bottom through which solid waste leaves the body. This is the end of the digestive system. This is where the digestive system in our human body ends.

The digestive system mainly breaks down food, and passes out the indigestive, from the anus. If we don’t have this system, we would be full of wastes. This system gives us what we need (nutrients) and takes out what we don’t need (wastes). The digestion mainly occurs in our mouth and our intestine. Other living things might use us, to help their life by us, digesting their foods.

The great Digestive system~ Yoshita Digestion is the breakdown of larger insoluble molecules into smaller soluble molecules that can pass through the wall of the gut into the blood. When we chew something with our teeth, it makes the food have a larger surface area. Then our saliva starts breaking the carbohydrate into sugar. The food is then pushed down the esophagus. Then from the esophagus to the stomach by peristalsis. This is the process of the digestive system.

Peristalses are the contraction and relaxation of the circular muscles in the wall of guts. When the muscle relaxes the food drops down and when it contracts at the top of the food at the bottom it is pushed down. The food is then in the stomach then churned around the peristalsis to make it mush and it mixes with the gastric juice. The gastric juice is always in our body. Everything in the digestive system is all about digesting the food we eat. This contains “enzyme” which breaks down proteins, it also contains “hydrochloric acid”, which kills bacteria.

The food is then released, a little bit at a time, into the first part of the small intestine. Intestines are long tubes in the body, between the stomach and the anus. There is one type of digestive juice called “bile”, and it helps the small intestine work more effectively. It is made by the liver and stored in the bag called “gall bladder”. The gall bladder neutralizes the acid that was added in the stomach. The bile also helps emulsify the fats, which means to make the fats into smaller blobs to make their surface area larger.

The bile is made by the liver and stored in a small bag called gall bladder.It then passes to the 2nd part of the small intestine. the intestine allows rapid diffusion of the products of digestion. There are villi walls in our body.

A system gives us what we need in our body and takes out what we don't need in our body. It occurs in our mouth and in our intestines. Carbohydrates are substances such as sugar or starch that consists of carbon, hydrogen, and oxygen. Everything we eat passes through our stomach. The food which cannot be digested will end up in the large intestine. The digestive system helps us in digesting our foods.

This system starts from the mouth. When we chew something with our teeth, it makes the food have a larger surface are. Then, our saliva starts changing the carbohydrates into sugar. Carbohydrates are substances such as sugar or starch that consists of carbon, hydrogen, and oxygen. It provides the body with energy and heat. The food is then pushed down the esophagus, to the stomach by the peristalsis. Peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When the muscle relaxes, the food drops down and when it contracts at the top, the food at the bottom is pushed down. The food is then pushed down the esophagus, to the stomach by the peristalsis. Peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When the muscle relaxes, the food drops down and when it contracts at the top, the food at the bottom is pushed down. Then, the food will go to the stomach. Here, the food will get churned around by more waves of peristalsis to make it into mush, and it mixes with one kind of acid, called “gastric juice”.

When you are hungry your stomach muscles contract. How does digestion start? Well first you chew something with your teeth. This makes the food have a larger surface area then your saliva starts breaking the food. The food is churned around by more waves of peristalsis to make it mush, and it mixes with gastric.

The Digestive System Miss it, you will panic in a moment. Looks yucky but, makes you experience what’s inside our body.

Do you know what digestion is? Digestion helps you when you eat. If you didn’t have the digestive system, you would have been filled up with faeces. Faeces are poo. Digestion is the breakdown of insoluble molecules into smaller molecules. First of all, the digestive system is kind of yucky and disgusting for me though if you didn’t get one your body will be very heavy unless you don’t eat every 3 meals fully. If the digestion is not successful, it becomes waste and comes out from our anus.

The digestive system starts from the mouth. First we chew food with our teeth and taste with our tongue. There are different parts of taste buds. Saliva seems to be disgusting but it helps you to swallow food. When you swallow them, the food is already fully chewed and it will look like a smoothie. When we vomit, it looks disgusting because we are spitting out already digested food. Sometimes, it stinks too! We make saliva every single minute. That’s why, we should drink 3 liters of water every day. The food is then pushed to the esophagus to the stomach by peristalsis. It contracts and relaxes every time.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">Peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When you are hungry, your muscles contract. We will get sick and tired if we don’t eat. The food also goes through intestines. Food is then in the stomach, and it is churned around by the waves of peristalsis to make it into mush and mixes with gastric juice. Gastric juice is also a type of acid.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">Gastric juice contains enzymes which break down proteins, and hydrochloric acid. Hydrochloric acid kills bacteria. You grow a new stomach lining every 3 days. Everything we eat ends up in our stomach. The food is then released a little bit a time into the duodenum. The gastric juice is actually in the stomach. It is an acid. Mucus protects our stomach walls from acid.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">There are 2 intestines in our body, the large and small intestines. Small intestines are 4 meters long for kids and 7 meters long for adults. Large intestines are 2 meters long. They are so long but they fit because they are all scrambled up. The reason why small intestines are longer is because the width is smaller and the length is longer. The intestine is specially adapted for absorption, passing digested food into the blood.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">One of the gastric juices comes from the pancreas and it breaks down lipids. Lipids are fats and oils. Another juice is called the “bile”. It helps the small intestine work better and effective. Gum is made of the same materials, and they are used to make tire and bits of chalk! Have you ever had hick ups? When we have hick up, our diaphragm gets squeezed very often. Fart makes sounds because there is the door and as the door opens, it will sound “broop” and smell.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">Each villi has a blood vessel and a lymph vessel to carry the food away. Then, it enters into the colon where most of the water is reabsorbed into the blood. The indigestible remains form semi solid faeces which is stored in the rectum. Before the small intestine, there are the “pyloric valves”. Pyloric valves open so food can get in the intestine. This is placed before the intestine.

<span style="font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt;">Under the rectum, there is something disgusting, but if you don’t have one, you will be full with waste. Anus is where pee and faeces comes out. The reason these 2 objects come out is because they couldn’t be digested. It takes hours and hours to be digested. Sometimes, it takes a couple of days. For example, if today is Thursday and you go to the toilet and poo, it would probably be Tuesday or Wednesday’s breakfast. Isn’t that cool? <span style="display: block; font-family: Calibri,sans-serif; font-size: 12pt; margin: 0cm 0cm 0pt; text-align: right;">Written by Ji Ae G5

<span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 12pt; line-height: 115%; text-align: center;">What is the digestive system? Do you know about it? Ok, I will explain to you. Digestive system is about the food that will come to body to digest. The digestive system is made up of a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Digestion is the breakdown of large insoluble molecules into smaller soluble molecules which can pass through the wall of the gut into the blood. Everything you eat ends up in our stomach. Carbohydrates, proteins, and lipids will be digested at different digestive organs. <span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 12pt; line-height: 115%; text-align: center;">Now, I will tell you how the food passes through our body. Digestion starts first in your mouth from your teeth which make the food break into small pieces and have a larger surface area. Then, your saliva will start breaking carbohydrates into sugar. You should slowly chew the food in your mouth. You shouldn’t use your teeth to chew hard food, for example, ice etc because your teeth could be broken. Can you guess where the food will go next? Then the food will go down to the esophagus.

<span style="display: block; font-family: Arial,Helvetica,sans-serif; text-align: center;"> Where will the food go next when they are at esophagus? When the food is pushed down, the food will go to the stomach by peristalsis. Peristalsis is the contraction and relaxation of the circular muscles which occur along the course of the intestinal tract to push food and waste products through. When the muscle relaxes, the food drops down. When the muscle contracts at the top, the food at the bottom is pushed down.

<span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 12pt; line-height: 115%; text-align: center;">The food then goes to the stomach to digest. The food is chewed around by more waves of peristalsis to make it into much, and it mixes with gastric juice. Gastric juice is produced in the stomach. Gastric juice contains an enzyme which breaks down protein. It also contains hydrochloric acid which kills bacteria. Beans and rice make a complete protein. The gastric juices in the stomach help the bowel to absorb some important substances from food like Vitamin B12, iron and calcium. You grow a new stomach lining every 3 days.

<span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 12pt; line-height: 115%; text-align: center;">Now, the food will move down to the first part of the small intestine. The small intestine is the longest portion of the digestive tract. Small intestine is more than 6 meters long. One of the juices comes from the pancreas and it breaks down the lipids. Lipids are facts and oils. The other digestive juices are called bile. Which is made by the liver and stored in a bag called the gall bladder but it neutralizes the acid that was added in the stomach. This helps the small intestine work more effectively and emulsifies the fats. Effectively means to make the fats into smaller blobs to make their surface area larger. So, the lipase can digest quicker.

<span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 12pt; line-height: 115%; text-align: center;">The food passes into the second part of the small intestine where enzymes complete the digestion. The intestine is specially adapted for absorption, passing digested food into the blood. It takes very long to allow time for digestion. The intestines have a very large surface area due to the presence of villi. All the food which cannot be digested ends up in the large intestine. The digestible food remains from a semi-solid faeces which is stored in the rectum. Eventually it is passed out the anus. So, the digestive system is very important because it helps you to breakdown the food and to send nutrients to your body. If you had no digestive system the wastes will be full in your body.

Do you know what digestive system is? It is a system which helps your food digest. The digestive system starts from your mouth. The digestive system also ends in your anus. The digestive system has two main organs. The two main organs are your small intestines and large intestines. Your intestines help you by mixing your food and making it into a smoothie. Our intestines are like mixers. They turn your food until they mix. Your small intestines take the nutrition’s from your intestines and pass it to your body.
 * The Journey of Digestion **
 * < Digestive system the yucky system> **

In your digestive system there is a tract which helps your food digest. First food enters from your mouth. Next food goes down through your esophagus. Then it enters your stomach. After that your intestines digest it. Then the rectum stores your food until it is ready to leave your body. Lastly the food comes out from your anus. Your anus helps your body by letting waste go out of your body. It comes out in the form of poop.

The small intestine is about 6 meters long. It is 6 times longer than an adult. That is very long it is about 600 centimeters. The small intestine is also a long narrow tube located inside your stomach. The small intestine is called small intestine because of its narrowness. Its twisted together. First the food molecules are broken down in your stomach. This process continues until the nutrition’s are small enough to pass through the tube’s lining. The nutrition’s seep into the blood that is flowing. After that they are stored in the liver and passed to different parts of the body . The large intestine is another organ which breaks down your food. Your large intestine absorbs with the food that the small intestine can’t. Your large intestines also help dealing with the food that your small intestine can’t. Then after your large intestine is done with dealing it the food turn to waste. After that the waste goes in the rectum and stays there until its ready to come out.

There is one organ called the liver. Liver is the body’s largest organ which performs over 500 tasks. One of its tasks is to make the nutrition’s in the blood that come from the small intestine. Once the blood has the right amount of nutrition’s needed it will be passed to the rest of the body. Liver is doing all the main parts for your body. Liver is also known to be an important organ in our bodies.

Finally we have finished with the Digestive System. Without your digestive system your body would die. Without your digestive system your body would die because it wouldn’t get enough nutrition’s. Your body will also die in a week because food is fuel for our body. Without your digestive system you wouldn’t be able to eat any morsel of food! DARSHAN G>5

This is my essay-Radhika

<The human body system.> Digestion is very important, because the food (waste) needs to come out of you anus. I know it’s disgusting, but if you don’t have one you will be filled with poo and pee. Digestion is the breakdown of large insoluble molecules into smaller soluble molecules which can pass through the wall of the gut into the blood. We drink about 3 liters of water a day.

When you are hungry your stomach muscles contract. How does digestion start? Well first you chew something with your teeth. This makes the food have a larger surface area then your saliva starts breaking the food. The food is churned around by more waves of peristalsis to make it mush, and it mixes with gastric. The food is released at a time into the duodenum, which the first part of our small intestine. One of the juices comes from the pancreas and it breaks down lipids. The large intestine is 2(two) meters long. The long intestine is 3 meter long.

<span style="color: #000000; font-family: Calibri,serif; margin-bottom: 0cm; text-indent: 0.64cm;">The food is then pushed down the esophagus, to the stomach by the peristalsis. Peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When the muscle relaxes, the food drops down and when it contracts at the top, the food at the bottom is pushed down. Then, the food will go to the stomach. Here, the food will get churned around by more waves of peristalsis to make it into mush, and it mixes with one kind of acid, called “gastric juice”. This contains “enzyme” which breaks down proteins, it also contains “hydrochloric acid”, which kills bacteria. Food is fuel. Food is now semi-liquid; it passes through the second part of small intestine. This allows vapid diffusion of products of digestion. This helps speed up the diffusion. Each villi has a blood vessel and a lymph vessel to carry the food away. It takes a long time to food to digest.

Do know what the other name is for esophagus? The other name for esophagus is “gullet”. The gullet is a tube that passes through your neck (throat) and your food passes down through the gullet. The process that pushes your food down to the stomach is called the “peristalsis.

Food comes out from our anus is because it is waste for our body, our body doesn't need it any more. So thats why it is important to for waste to come out from our body. But the waste smells bad because it was inside your body for quite long time so suddenly it comes out, so it smells. I know its disgusting, but what can i do.

Digestion is very important to our body. It is important to digest food, because you will feel heavy in your body and you will be filled with poo and pee. The digestive system is the systems that digest the food that you ate; sometimes it might take days or hours to digest food.

Do you know what the digestive system is? The digestive system is the process of digestion. Digestion is the breakdown of large insoluble molecules into smaller soluble molecules which can pass into the wall of the gut then into the blood. Our digestion first starts to begin in your mouth. When you start chewing with your teeth, it makes the food have a larger surface, and then the food can easily go down your stomach, and start digesting a lot. Digestion is very important. ======

=
It takes a very long time for food to digest. It takes up to two days for food to fully complete digesting. When you swallow, the food is pushed down the esophagus then to the stomach by the peristalsis. The food that is in the stomach is then chummed around by more waves of peristalsis to make it into mush, and then it gets mixed with gastric juice. After the stomach the food is then released to the small intestine. ======

=
Gastric juice is a type of liquid in your body that contains enzyme which breaks down protein in your body. It also contains hydrochloric acid which kill all the bacteria that are inside your body. One of the types of gastric juice comes from the pancreas. The gastric juice that comes from the pancreas breaks down into these things that are called lipids. Lipids are the fats and oil that is in your body. ======

=
There is also something in your body that is called the bile. The bile also makes the fats in your body into smaller blobs. The bile is made by something in your body called the liver and is stored in a bag called the gall bladder. Another thing that the bile does is it helps the small intestine work more effectively. The bile is also known as another type of gastric juice that is in your body. ======

=
The small intestine in your body is about six meters long. When the food is all in your body, it gets mixed like a smoothie. After it becomes like a smoothie, it goes down to the second part of the small intestine. Seeds cannot be digested (seeds of fruits). The food that cannot be digested has to go down the large intestine, and the food that can be digested goes down the small intestine. ======

=
In the end all the food starts to pile up and come out of the anus. The anus is the opening hole that allows all the digested food to come out as poop. It is very hard for food to digest. The digestive system is very important. That is all about the digestive system. ======

Digestive System -Natcha <span style="display: block; font-family: Calibri; font-size: 12pt; line-height: 115%; text-align: center;">Digestive System in Human Body <span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">Digestion is the breakdown of large insoluble molecules into small soluble molecules which can pass through the wall of the gut into the blood. The other meaning of digestive system can be how food goes in and how the food comes out. Do you know? That it takes tow day for food to be digested. You should eat healthy food because it’s good to give healthy food to your body. If there will be no digestive system in your body, it means you can’t eat anything!

<span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">How does your digestive system start? Well, first you chew something with your teeth. Food has a larger surface area and your saliva will help breaking the food carbohydrates into sugar. After that the food passes down into the stomach and churning around by more waves of peristalsis to make it as much. Peristalsis is the contraction and relaxation. There is an acid in your stomach which can make the food digest, the acid can also break through the skin, mucus help to protect you wall from acid.

<span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">Do you know where does your food go after your stomach? It goes to your small intestine. Your small intestine is about 6 meters long. One of the juices comes from the pancreas and it break down into lipids. What are lipids? Lipids are fat and oil in your body. There is not just one juice but much kind of juices in your body.

<span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">The other digestive juice is called bile. Bile is made up of liver and stored in bag called the gall bladder but it neutralizes the acid that is added in the stomach. It helps the small intestine work more effectively. Bile also helps emulsify the fats. Emulsify means making the fat into smaller pieces to make their surface area larger. Then it passes into second part of small intestine. The wall of ileum makes a digestive juice. The food in small intestine is taken as portions etc.

<span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">The intestine have very large surface area clue to presence of vili. Vili allows rapid diffusion of product of oligestion. The vili wall is only one cell thick. This helps speed up the diffusion. Each vili has a blood vessel and a lymph vessel to carry the food away. All the food which can’t be digested ends in large intestine. The indigestive remains from a semisolid faces which is stored in the rectum. At last it passes out the anus. <span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">Some fast fact to know! When you think of food think as it is a fuel. You grow a new stomach lining every three days. You should drink three litters of water every day. Your large intestine is 2 meter long. Your digestive system start in your mouth ends up at anus. Don’t forget to eat!!!!

<span style="font-family: Calibri; font-size: 12pt; line-height: 115%; margin: 0cm 0cm 10pt; text-indent: 21.3pt;">Digestion is the breakdown of large insoluble molecules into small soluble molecules which can pass through the wall of the gut into the blood.

Digestion means breaking down of large insoluble molecules into smaller soluble molecules that can pass through the wall of the gut into the blood. It first started in the mouth with you chewing. Now the food is pushed down to the esophagus to the stomach by peristalsis. Then the food is pushed down the stomach and gets digested. It passes through your small intestine. The villi take in the goods and nutrients in the food. The waste goes in the large intestine and it goes out your anus. The body contains many things. The peristalsis is the contraction and relaxation of the circular muscles in the wall of the gut. When the food is in your stomach the food is churned around by more waves of peristalsis to make it into much and mixed with gastric juice. There is a type of acid called hydrochloric acid. Hydrochloric acid can pass through metal or skin. You should be carful of acid. Gastric juice contains enzyme and it breaks down protein. It also contains hydrochloric acid which kills bacteria. Then the food is pushed in duodenum which is the first part of the small intestine. The small intestine has more stuff. The small intestine connects to the large intestine. Lipids are fat and oil in our body. Bile is another digestive juice. Bile is made in our liver. It is stored in a bag called the gall bladder. It isn’t an acid which burned. The liver is little bit up of our body. The liver is actually brown. The liver is important part in our body. Without is you would die. Now the small intestine is the intestine that takes in goods. The small intestine allows absorption of goods. The Villi will absorb goods. The waste goes in the large intestine and out of your anus. The anus is the opening or and exit for the waste to go out from your body. The body does hard work. The food takes a lot of time to digest. Snakes digestion can take 2 years to digest. Some food is good some are bad. Fat can make you fat that’s why it is called fat. These things are important.
