PATHOLOGY

Detailed explanation-1: -Peristalsis is the involuntary contraction and relaxation of longitudinal and circular muscles throughout the digestive tract, allowing for the propulsion of contents beginning in the pharynx and ending in the anus.

Detailed explanation-2: -Peristalsis is the automatic wave-like movement of the muscles that line your gastrointestinal tract. Peristalsis moves food through your digestive system, beginning in your throat when you swallow and continuing through your esophagus, stomach and intestines while you digest.

Detailed explanation-3: -The peristaltic reflex, first described in detail by Bayliss & Starling (1899), is a fundamental reflex that propels gastrointestinal content in an oral to anal direction. The peristaltic reflex contributes aboral propulsion of content through the small and large intestines.

Detailed explanation-4: -Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
