peristalsis
peristalsis (pe-ri-stal-sis) n. a wavelike movement that progresses along some of the hollow muscular tubes of the body, such as the intestines. It occurs involuntarily, induced by distension of the walls of the tube. Alternate contraction and relaxation of the circular and longitudinal muscles tends to push the contents of the tube forward.
—peristaltic adj. |
