Answer:
In the esophagus, wavelike movements called peristalsis move food towards the stomach.
Explanation:
The esophagus is lined with smooth muscles. The function of the esophagus is to deliver food from pharynx to the stomach.
Peristalsis refers to the wave-like movement generated by the rhythmic contraction of smooth muscles. Alternating contraction and relaxation of smooth muscles that line the cavity of esophagus generate waves. This wave-like movement moves the food from esophagus to the stomach.
