Detailed explanation-1: -Overview. Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
Detailed explanation-2: -Peristalsis is a type of involuntary muscle movement that occurs in your digestive system. It begins in your throat when you swallow, and continues to propel food and fluids throughout your gastrointestinal tract.
Detailed explanation-3: -A series of normal coordinated, rhythmic muscle contractions, that occurs automatically to move food through the digestive tract is called peristalsis.
Detailed explanation-4: -Smooth muscles act by involuntary peristalsis, moving food through the digestive system.
Detailed explanation-5: -Two types of movements take place in the gastrointestinal (GI) tract; peristalsis and segmentation. 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.
