What is perisalisis?

Answer 1

Peristalsis is a rhythmic, wave-like muscle contraction that occurs in the digestive tract, primarily in the esophagus, stomach, and intestines. This coordinated movement helps to propel food and liquids through the digestive system, facilitating digestion and absorption of nutrients. It is an involuntary process, controlled by the autonomic nervous system, ensuring that the contents of the digestive tract move in a continuous manner.
