what is peristalis in biology? Explain
Answers
Answer:
The process of wave-like muscle contractions of the alimentary tract that moves food along is peristalsis. (Science: gastroenterology, physiology) The wormlike movement by which the alimentary canal or other tubular organs provided with both longitudinal and circular muscle fibres propel their contents
Answer:
Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction.
Explanation:
In much of a digestive tract such as the human gastrointestinal tract, smooth muscle tissue contracts in sequence to produce a peristaltic wave, which propels a ball of food (called a bolus while in the esophagus and upper gastrointestinal tract and chyme in the stomach) along the tract. Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward.
