digestive system?</h3>
The digestive system of the human body is made up of the gastrointestinal tract and additional digestive organs.

Cephalic, gastric, and intestinal phases make up the three stages of the digestive process. Peristalsis is the term used to describe the rhythmic contraction of muscles that starts in the esophagus and travels down the stomach wall and the rest of the gastrointestinal tract.
