Final answer:
Peristalsis takes place in the esophagus and the intestines. It is responsible for pushing food through the digestive system.
Step-by-step explanation:
Peristalsis takes place in the esophagus and the intestines. The esophagus is a tubular organ that connects the mouth to the stomach, and the smooth muscles of the esophagus undergo a series of wave-like movements called peristalsis that push the food toward the stomach. In the intestines, peristalsis is responsible for moving food and waste through the digestive system.
