PeristalsisDefinition Peristalsis is a series of coordinated, rhythmic muscle contractions that occur throughout the length of the gastrointestinal tract. Peristalsis is also seen in the ureters, which are tubular organs that connect the kidneys to the bladder. It is an automatic and vital process that moves food through the digestive tract, urine from the kidneys through the ureters into the bladder, and bile from the gallbladder into the duodenum. Peristalsis is a normal function of the body to move fluid from one place to another. It can sometimes be felt in the abdomen as gas moves along. Peristaltic waves look like the muscle contractions of a snake's underbelly that enable it to move along a surface. Illustrations
