Digestive System By Jorge Avila and Luis Loredo

2 The Mouth Digestive system starts in the mouth
The mouth is chemical and mechanical The saliva helps the mouth digest the food After the mouth the food goes to the esophagus

3 The Esophagus The esophagus is mechanical because it squeezes the food trough the throat The movement of the esophagus is by peristalsis After the esophagus the food goes to the stomach

4 The Stomach As the food enters the esophagus the stomach expands and the folds smooth out Mechanical and chemical digestion happen in the stomach The food will next go to the small intestine

5 The small intestine As chyme leaves your stomach it enters the first part of your small intestine, called the duodenum Most digestion takes place in the duodenum Then the chyme goes to the large intestine

6 The large intestine When the chyme enters the large intestine it is still a watery mixture Peristalsis usually slows down the large intestine After the large intestine chyme goes to the rectum/anus

7 Rectum/Anus The rectum/anus is were the food is thrown out of your body The anus is mechanical The anus is the end of the digestive system

8 This is a model of all the parts of the digestive system
