Answer:
Explanation:
Alternating contraction and relaxation of these muscles is called peristalsis. Peristaltic waves push the swallowed bolus down the esophagus. In the stomach, peristalsis churns swallowed food, mixing it with gastric juices. These mechanical and chemical actions further break down food into a substance called chyme.
