Peristalsis is a radially symmetrical contraction and relaxation of muscles which propagates in a wave down a muscular tube, in an anterograde fashion. Peristalsis is often found in the contraction of smooth muscle tissue to propel food/chyme through a digestive tract, such as the human gastrointestinal tract.
