Peristalsis Definition Anatomy

In the stomach this motion mixes food with gastric juices turning it into a thin liquid. The rippling motion of muscles in the digestive tract.

Physiology Of Peristalsis

Peristalsis a coordinated succession of contractions and relaxations of the muscular wall of a tubular structure such as the oesophagus small intestine or the ureter producing a wave like pattern whose effect is to move the contents along.

Peristalsis definition anatomy. Alternating contraction and relaxation of these muscles is called peristalsis. Peristalsis is the contraction of muscle tissue that helps move and break down foodstuffs the walls of the alimentary canal include layers of smooth muscle controlled by the autonomic nervous system. Peristalsis definition is successive waves of involuntary contraction passing along the walls of a hollow muscular structure such as the esophagus or intestine and forcing the contents onward.

Peristaltic waves occur in the esophagus stomach and intestines. Peristalsis definition peristalsis the rhythmic waves of contraction that move food through the gastrointestinal tract. Peristalsis involuntary movements of the longitudinal and circular muscles primarily in the digestive tract but occasionally in other hollow tubes of the body that occur in progressive wavelike contractions.

Pressure against the inner walls of the intestines such as occurs when food enters an intestinal segment signals the muscles to contract and relax in a progressive pattern. In the stomach this motion mixes food with gastric juices turning it into a thin liquid.
