Where Does Peristalsis Occur. Peristalsis occurs throughout the digestive tract. It begins with the primary peristaltic wave in the esophagus as you swallow food from your mouth to the stomach. As food enters your stomach these muscular movements continue right through to your anus, where waste is eliminated from the body.
Peristalsis is a radially symmetrical contraction and relaxation of muscles which propagates in a wave down a muscular tube, in an anterograde fashion. In humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract.It is wave contraction of longitudinal and circular muscles preceded by wave relaxation of these muscles. Earthworms use a similar mechanism to drive their locomotion.n humans, peristalsis is found in the contraction of smooth muscles to propel contents through the digestive tract.
