Answer:
Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. ... The strong wave-like motions of the smooth muscle in the esophagus carry the food to the stomach, where it is churned into a liquid mixture called chyme.

Peristaltic Waves Move Nutrients and Waste Through the Intestines.
Peristalsis is a normal function of the body. It can sometimes be felt in your belly (abdomen) as gas moves along.An ileus and an intestinal obstruction have similarities, but an ileus results from muscle or nerve problems that stop peristalsis while an obstruction is a physical blockage in the digestive tract. However, a type of ileus known as paralytic ileus can cause a physical block due to a buildup of food in the intestines.Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.They serve to expose food to the intestinal wall for absorption and to move it forward. In the large intestine (or colon), the peristaltic wave, or mass movement, is continuous and progressive; it advances steadily toward the anal end of the tract, pushing waste material in front of the wave.
