Answer:
With each swallow a structure called the epiglottis closes over respiratory structures. The swallowed bolus stays on course and is directed toward the esophagus. One peristaltic wave can be enough to move a bolus down the esophagus and into the stomach.
Explanation:
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. ... In the large intestine peristalsis helps water from undigested food be absorbed into the blood stream.
