Answer:
Peristalsis is the right answer.
Step-by-step explanation:
Peristalsis is a set of wave-like brawn tensing that transfers food to various processing channels in the digestive tract. The method of peristalsis occurs in the esophagus while a bolus of the meal is consumed. The powerful wave-like movements of the soft muscle in the esophagus bring the food to the stomach, where it is mixed into a watery mixture known as chyme.
