Digestive System

Dear world,

Today I am going to tell you about the digestive system.

The first thing that happens in your digestive system is you take a bite a food. Your teeth, saliva, and tongue all work together to break down the food. There are two types of digestion chemical and mechanical.  The macanical The tongue then pushes the food then goes down you esophagus to your stomach. Your stomach churns the food and also releases chemicals to break down the food even farther from what just happened in your mouth. From there the food enters your little intestine where the villi take in all the nutrients and send the nutrients to your blood stream. Next, food goes into the large intestine where the liquid is sucked out of the food this helps keep you hydrated. The final thing that happens in your digestive system is all the food gathers at the rectum until your rectum gets full. Next time to rectum gets full thats when you need to go to the bathroom.
