Digestive System By
Jorge Avila and

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
