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.
A time-space diagram of a peristaltic wave after a water swallow. High pressure values are red, zero pressure is blue-green. The ridge in the upper part of the picture is the high pressure of the upper esophageal sphincter which only opens for a short time to let water pass.Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction. The primary peristaltic wave forces the bolus down the esophagus and into the stomach in a wave lasting about 8â9 seconds. 2  The wave travels down to the stomach even if the bolus of food descends at a greater rate than the wave itself, and continues even if for some reason the bolus gets stuck further up the esophagus.
