This thing is a project about the digestive system

Storyboard Text

  • The digestive system starts when a person eats. His mouth's teeth by chopping and grinding the food allow him to do mechanical digestion. The enzymes in his saliva allow him to digest even more
  • The food goes down the esophagus with muscle movement known as peralstasis.
  • The food falls into the stomach. Enzymes in the stomach turn it into small molecules and soon into a soup with a thick texture.
  • The souplike broken down food, or chyme moves from the churning stomach of acid into the small intestine, which is actually seven meters long! In the first part of the small intestine called the duodenum, digestive enzymes from the liver and pancreas join the mix to make the molecules small enough to absorb into your blood stream.
  • The chyme that has been made into a molecule mix small enough to be put into your blood moves through the small intestine where tiny fingerlike things called villi gather the nutrients of the chyme flowing by and putting it in the bloodstream
  • When chyme gets to the shorter large intestine, it is thin and watery. The walls of the large intestine sucks most of the water out of digested chyme in a process called absorption so that you don't get dehydrated. When most water is gone, solid waste goes to the rectum at the end of the large intestine
  • When enough waste piles up there, you poop and the 2-3 day digestion is finished
