Detailed explanation-1: -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: -Peristalsis squeezes your esophageal muscles from top to bottom. This pushes food and liquid along. If you could see peristalsis, it would look like a wave passing down your esophagus. To keep food and liquids moving in the right direction, your digestive tract has special muscles along its course called sphincters.
Detailed explanation-3: -Peristalsis is the automatic wave-like movement of the muscles that line your gastrointestinal tract. Peristalsis moves food through your digestive system, beginning in your throat when you swallow and continuing through your esophagus, stomach and intestines while you digest.
Detailed explanation-4: -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.
