Explanation:
Detailed explanation-1: -Overview. 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-2: -Primary peristalsis is initiated by a swallow and is the main source of esophageal transit whereas distension-induced or secondary peristalsis functions to maintain an empty esophagus by clearing refluxate from the stomach [1] in the absence of swallowing.
