Detailed explanation-1: -Peristalsis occurs throughout your GI tract, but especially in your esophagus. When you swallow, your throat (pharynx) begins the process by pushing food and fluids down into your esophagus (food pipe), which leads to your stomach.

Detailed explanation-2: -peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.

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: -Expert-Verified Answer. The movement of food through alimentary canal by the wavelike movement controlled by involuntary muscles is called Peristalsis.

Detailed explanation-5: -Muscularis propria (externa): smooth muscle layer. These layers of smooth muscle are used for peristalsis (rhythmic waves of contraction), to move food down through the gut.
