Step 1: Define peristalsis.
Peristalsis is a series of wave-like muscle contractions that move food along the digestive tract. It occurs in the esophagus, stomach, and intestines.

Step 2: Conclusion.
Thus, the contraction and expansion movement of the wall of the food pipe is called peristaltic movement.
