The digestive system. Here it starts in the mouth. Here food is broken up by the teeth and mixed up with saliva by the tongue. Then it goes to the esophagus.

Here in the esophagus, food goes in this tube to the stomach. Here in the stomach, there is gastric juice and it makes thick liquid. Then it goes to the small intestine.

Here there are a lot of blood vessels and nutrients go to the blood, then it goes to the large intestine.

Here the waste passes through here and the water goes out into the body and then the waste becomes hard.
