Peristalsis is simply a series of muscle contractions, these contractions occur in the digestive tract
Peristalsis is also observed in the tubes that connect the kidneys to the bladder
Peristalsis is an automatic and important process which moves: food through the digestive system, urine from the kidneys into the bladder and bile from the gallbladder into the duodenum
Peristalsis is a normal function of the body and can sometimes be felt in the belly (abdomen) as gas moves along
