Peristalsis: Definition, The Process Of Food Movement

WebWhen you swallow, food travels down the esophagus by a series of muscular contractions called peristalsis. At the bottom of the esophagus is a muscular valve (the lower esophageal sphincter or LES) that opens to allow food to enter the stomach and then closes to prevent regurgitation of stomach contents back into the esophagus. WebThe contraction wave which starts high up in the pharynx and progresses down the whole length of the esophagus is initiated by the voluntary act of swallowing. This wave is called primary peristalsis (figure 1).
