Peristalsis is a series of muscle contractions that occur in your digestive tract. Peristalsis is also seen in some organs that connect the kidneys to the bladder.
Peristalsis is an automatic and important process. It moves:
- Food through the digestive system.
- Urine from the kidneys into the bladder
- Bile from the gallbladder into the duodenum
Peristalsis is a normal function of the body. It can sometimes be felt in your belly (abdomen) as gas moves along.
