Detailed explanation-2: -Peristalsis is a type of involuntary muscle movement that occurs in your digestive system.

Detailed explanation-3: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-4: -Smooth muscles act by involuntary peristalsis, moving food through the digestive system.

Detailed explanation-5: -Esophageal peristalsis results from sequential contraction of circular muscle, which serves to push the ingested food bolus toward the stomach. Esophageal longitudinal muscle may also play a role in peristalsis.
