  2. Farting is the way the body releases excess gas that builds up within the intestines throughout the day The gases that are released include oxygen, carbon dioxide, methane and hydrogen sulfide the smell is the hydrogen sulfide.

  3. There is a pigment called bilirubin that is formed when the red blood cells in the liver and bone marrow break down. This ends up in the intestines where bacteria begins to form and eat which turns the poop brown.

  5. Why do we burp?
    because somethings when you eat and drink you sometimes also inhale air into your stomach and when that happens the air rises and comes out our mouth which = Burping

  7. Why do we have teeth?
    Teeth help us the tear, cut and break up food into tiny pieces so that they are easier to swallow and digest.

  9. When these muscle contractions get going again and your stomach is empty, those gas and air pockets make a lot more noise that you hear as stomach growling.

  15. Why does our belly rumble when we are hungry? Our stomachs contract to clean up any thing missed, so when our stomachs contract when they're empty the air and gas pockets make more noise

  16. teeth are extremely useful. they help the tear, cut and break up your food into very small pieces so you can swallow it more easily. Digestion starts in your mouth with your teeth. Omnivores eat plants and animals so they need different kinds of teeth, each kind is designed to break up different types of food.

  17. why do we have individual teeth?
    Individual teeth provide redundancy in case a problem arises in one tooth
    Individual teeth are advantageous for development of the dentition and jaws
    Individual teeth allow adaptation to function
    Formation of individual has less energy demands

  18. Why do we have teeth? We have teeth to break down our food so we can digest our food

  19. Why do we have teeth?
    Teeth are very useful. They help us to tear, break up and chew food. If we didn't have teeth and needed to swallow large bits of food, we would probably choke. Teeth also help us to form words to speak properly.👍

    1. Leftover soil particles and undigested organic matter pass out of the worm through the rectum and anus in the form of castings, or worm poop. Worm poop is dark, moist, soil-colored, and very rich in nutrients. That's why farmers and gardeners like to have lots of worms in their soil

    2. yes there poo is like a very fertile dirt

    1. if you had a pill or a liquid it does but if you have a needle then no because it go into your blood stream

    2. When you take medicines by mouth, they travel through the digestive system and are then taken up by internal organs like the stomach and small intestine. Most of the time, they are then sent to the liver, where they might be chemically modified and then they are released into the bloodstream.
