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: -The rippling motion of muscles in the intestine or other tubular organs characterized by the alternate contraction and relaxation of the muscles that propel the contents onward.
Detailed explanation-3: -The intestines process your food along this journey through a series of wave-like movements called peristalsis. Paralytic ileus is the paralysis of these movements. It means that the muscles or nerve signals that trigger peristalsis have stopped working, and the food in your intestines isn’t moving.
Detailed explanation-4: -Esophagus. After you swallow, peristalsis pushes the food down your esophagus into your stomach.
