Peristalsis

• Overview

Definition:

Peristalsis is a series of organized muscle contractions that occur throughout the digestive tract. Peristalsis is also seen in the tubular organs that connect the kidneys to the bladder.

Peristalsis is an automatic and important process that moves food through the digestive system. It also moves urine from the kidneys into the bladder, and bile from the gallbladder into the duodenum .

Peristalsis is a normal function of the body. It can sometimes be felt in the abdomen as gas moves along.

Alternative Names:
