Digestive System

Ladies and Gentlemen,

Please use this post to complete your assignment(s) focused on the digestive system.

Thanks for pushing your thinking!

Mr. Moore, Ms. Vander Velde, and Ms. Thumm


  1. Dear Mr. Moore,
    The things I learned were very interesting and a tiny bit disgusting. I learned how the the system has 5 main parts: mouth, esophagus, stomach, small intestine, and large intestine. The food would go down the mouth, into the esophagus, then the stomach, and soon the small and large intestine. Also, I learned how the stomach has acid in it and that the food would be churned by enzymes. Soon break down and go down the small intestines. There, I learned the small intestines absorb the nutrients and by getting that, small little finger, or what ever it looks like called villi absorbs the nutrients. Then, goes into the large intestines. That was where the the water and mineral was absorbed. Finally, the waste escapes the body. Quite disgusting to many. But, very interesting indeed. I can't wait to keep going on the assignment because I love Biology!

  2. Dear Mr.Moore
    In the three videos I learned more on how the digestive system works and how it works with other systems in the human body like for example after about 4 hours in you stomach the food is as thick as a thick milkshake and the small intestine is were almost all the nutrients is absorbed And that is all the villi that takes the nutrients. The large intestine suck all the liquid out of the food or chyme and that is called absorption. The last part of this long process is that food goes through the rectum.

  3. Dear Mr. Moore,
    I had learned that the food goes through the mechanical digestive process and it happens int the mouth. Then it travels through the esophagus. Next it goes through a physical and non physical digestions. Then through the duodena is the first small part of the small intestine. While it is traveling through the small and big intestine. Then it will come out of the body. It could take up to three to four days for this process.

  4. Dear, Mr. Moore, Ms. V, and Ms. Thumm,
    On Brain Pop I learned That food can be digested in two ways. One is called mechanical digestion. Mechanical digestion is the fiscal breaking down of food. The other is called chemical digestion. That is when your own chemicals help break down food. They both occur in the mouth.

  5. Dear Mr.Moore,

    I learned that food may take up to two or three days to completely digest. Also, After food goes out of the small intestine it is called chyme. I learned that the gas that breaks up food in your stomach is toxic but the reason it doesn't burn your stomach is because there is a thick layer of mucus inside of your stomach. I learned that chewing is called mechanical digestion and saliva and enzymes are called chemical digestion.

  6. Dear Mr. Moore and Ms. V,
    The digestive system is made of the mouth, esophagus, stomach, small intestine, large intestine and pancreas. All of thease are the organs in the diegestive system. We need energy to do the smallest thing, like just blink! vili helps deliver nutrions to the blood stream.

  7. Dear Mr.Moore,
    I learned (on Brain Pop) that there are two digestive systems that help they are called Mechanical Digestive and the second one is Chemical Digestive. The Mechanical System to it helps by breaking the food. The Chemical System to your body helps because the insinzes that you have break it down through the Moluccas that your body absorb! Both of those things that I just wrote happen in your mouth. The small intestine isn't that small in fact it is 7 meters long!

  8. Dear Mr.Moore,
    Today I learned how the Digestive system works. The first thing that happen in your digestive system is that the food you eat goes down your esophagus. Then it goes into your stomach were acids break down the food. After the stomach the food goes into your small intestine. In your small intestine villi suck out all the nutrient from the food and delivers it into your blood stream. After that the food goes into you large intestine. This is were all the moisture that is in the food gets squeezed out. Finally the waste goes into the rectum and gets it out of your body. This is a process that takes about four hours.

  9. Dear Mr. Moore,

    I learned in the Brain Pop video When you take a bite of food it goes to your mouth and your teeth and saliva work together to brake down the food. After it has been broken down, the food goes straight down to your esophagus. The esophagus leads the food to your stomach. In side of your stomach food is turned and mix with enzymes. Than the food goes into your small intestine. In the first part small intestine, the liver and pancreas give juice to help brake down the food more. In side of your small intestine, Villi collect nutrients to your cells while it goes by. After the small intestine the food goes to your large intestine where it suck lot of your moister out. Also it absorbs it means hold all of the moister. The liver and the Pancreas comes together to help brake down the food more and more by giving juice. Than it goes to your duodenum witch leads to your end part. After all that happens, it goes to your rectum which means you are ready to go to the bathroom and do your stuff. In the discovery Education I learned that your body gets nutrient from the food you get. Your needs nutrient which is energy that lets you do active things. The digestive system is made out of organ. The organ help brake down the food so your body can use it. Your teeth and tongue work together to mix and crush the food until it is soft and mushy. When you eat a bit of something, saliva moister and began to brake down food. When you shallow the food your throat push the food into a tube called esophagus. Than that tube muscle leads the food to the stomach. Your stomach still mix with acid and other stuff to brake it down. After it is done it goes into the small intestine. Finally nutrient from the food are absorbed through the walls of the small intestine. After that it goes to the large intestine. Than you are ready to go to the bathroom.

  10. Dear Mr. Moore,
    Here are some things I have learned from the various resources you provided us: First of all, there are two types of digestion, mechanical and chemical. Mechanical digestion is the actual breaking up of the food with your teeth and tongue-like the way I'm chewing this apple right now-and chemical digestion is the breaking up of the food into molecules that your body can absorb by chemicals known as enzymes. Both types of digestion occur in our mouths. We chew mechanically, and our toungue releases enzymes in the form of saliva. When the food you eat becomes soft enough, your tongue pushes in to the esophagus at the back of your mouth. The esophagus then contracts and squezes the food down into the stomach, where food is churned and mixed with enzymes. These chemicals break down proteins and fats. A lining of mucus protects your stomach from the acid. After about four hours in your stomach, food is the consistency of a thick milkshake and we call it chyme. The chyme then moves into the small intestine, which is about seven meters long, and then the nutrients in the chyme are absorbed. In the first part of the small intestine-called the duodenum-digestive juices from the liver and pancreas help digest the food further. They turn the chyme into a liquid compound of molucules small enough to be absorbed into your bloodstream. These molucules get absorbed by the villi and the waste travels out of the small intestine. At this point in digestion, the chyme is thin and watery, so it needs to be solidified before it exits the body. Thats where the large intestine comes in. (Even though the large intestine is shorter than the small intestine, the large intestine is wider.) The large intestine sucks most of the water out of digested chyme in a process called absorption. This step is important, because recovering that water keeps you from getting dehydrated. Once most of the water is gone, solid waste is moved to the last part of the digestive system, the rectum. After enough waste piles up their, you excommunicate it from your body and the digestive process is complete. The whole digestion process can take up to two or three days.

  11. Dear Mr.Moore, Ms.Vander Velde, and Ms.Thumm
    As I read about the digestive system on discovery science I learned that your organs work together to mix and crush your food. It mixes and crushes in till the food is soft and mushy. I also learned that your tongue moves your food back when you swallow, your throat pushes it down in your esophagus. That tube has muscles that move the food down into your stomach. The coolest thing that I learned was that you stomach mixes your food with acids and digestive juices. The next step is the food moves from your stomach into a long, winding tube. the tube is called your small intestine. If you stretch the long intestine out, it would be more than six meters long! Food gets broken down into small nutrients in this step. Finally, nutrients from the food are absorbed through the wall of the small intestine. They enter into tiny blood vessels. Your blood carries the nutrients to all the parts of your body.
    Your Student,

  12. Dear Mr. Moore,
    I learned that when you eat food the liver and the pancreas make acids to help brake-down the food. I also learned that if you streched out your small intestine it can be 6 to 7 meters long. One more thing I learned is that the small intestine is called that because it is thiner. The large intestine is thicker. Thank you for the links on the vocabulary words that was cool too.

  13. Dear Mr. Moore, Ms.V, and Ms. Thumm,

    The way the food goes through the body is:

    You take a bite a food and your teeth and saliva all work together to break down the food. The food then goes down you esophagus to your stomach. Your stomach churns the food and also releases cemicials to break down the food even farther. From there the food enters your little intestine where villi takes in all the nutrients. Next, food goes into the large intestine where the liquid is sucked out of the food. And finally all the food gathers at the rectum until the next time you go to the bathroom.

  15. How food goes through our body.
    It first goes through your mouth and you breakdown the food with your teeth. Then is goes through your esophagus, then the stomach, then to your liver. What else it goes to your small intestine and after that it goes to the large intestine. What else I know is that your esophagus is a long tube and then the stomach breakdown the food into digestion. This is what I know about the digestive system.

  16. Dear Mr.Moore, Ms.V, and Ms.Thumb

    When you eat your food it goes to your mouth, and get chewed up with your teeth and saliva,and tongue.Next after it goes to the esophagus, and into the stomach, it stays there for awhile until the chemical break up the food.After that it goes to the small intestine (Which is actually longer than Large intestine, this is were it takes all the nutrition . After swirling around the small intestine, it goes into the large intestine.Lastly it swirling around the large intestine, this is were the waste is sucked and takes all the water ,then lastly it goes out of the rectum, and repeats every time you eat.

  17. Dear Mr. Moore,
    What I learned in the videos was when you eat your saliva and your teeth break down your food so it can go down the esophagus to the stomach. When the food is in the stomach it churns it and it releases chemicals to break it down again. Then, the food enters the small intestine where the villi takes all the nutrients. Next, it goes in to the large intestine where liquid is sucked out. finally,the food travels to the rectum until you go to the restroom.

  18. Dear Mr.Moore, Mrs.V, and Mrs. Thumm,
    This is how the digestive system works, first it gets chewed with your saliva teeth and tongue. After it goes into the esophagus and into the stomach. It takes a while because there is a chemical that brakes up the food. After that, it goes to the small intestine, which takes the food to the large intestine where liquids are taken out. When you go to the restroom that's the end of the digestive system.

  19. Dear, Mr. Moore, Mrs. Thumm and Mrs. V

    My clear understanding in the system of digestion is that step one is that we eat and the food is crushed up in the mouth due to teeth and along with that is the saliva. Next step is when the food that has benn digested for a period is gone into the esophagus and then is transfered to the stomach and there is more digestion. Than the step the food takesis down a valve to the small intestine. and the most nutrients reach a certain blood valve called the villi. And so far the food has been broken down and is about to enter the big intestine. That is when fluid inside the waste is brung to the blood stream,. if that were not supposed to happen you wuold become dehydrated in a very short amount of time. The waste is entered the rectem in tiome for you to use the bathroom.

  20. Dear, Mr.Moore Mrs.v and Mrs.Thumb
    I learned in Brain pop it can take up to two or three day so the food can digest throgh your body. First you chew up your food then it gose throgh your esophagus to the stomach. Then the food enters the small intestinse where the villi takes the nutrents. Next it gose through the large intestins where the liquid is sucked. Finally you have to go to the bathroom.
