Answer 1

Peristalsis

Explanation:

• 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
