Peristalsis is a wave-like movement of muscles in the digestive tract that helps move food through your body. It's like when you squeeze a tube of toothpaste, and the toothpaste comes out in a long, smooth line. The muscles in your digestive tract squeeze and relax in a wave-like motion, pushing food down the tube from your mouth to your stomach, small intestine, and large intestine. Peristalsis is what keeps food moving through your body so you can digest it properly.
The peristaltic contractions of the colon help to move waste products out of the body.

Adjective:
