Peristalsis. Peristalsis is the process of involuntary wave-like successive muscular contractions by which food is moved through the digestive tract. The large, hollow organs of the digestive system contain muscle that enables their walls to move. The movement of organ walls can propel food and liquid and also can mix the contents within each organ. Typical movement of the esophagus, stomach, and intestine is called peristalsis. The action of peristalsis looks like an ocean wave moving through the muscle. The muscle of the organ produces a narrowing and then propels the narrowed portion slowly down the length of the organ. These waves of narrowing push the food and fluid in front of them through each hollow organ. See also borborygmus. The process of peristalsis is used by peristaltic pumps.
