Answer 1

Explanation:

Peristalsis is primarily found throughout the gastrointestinal tract and is the involuntary propulsion of food. This movement begins in the pharynx, once a food bolus is formed, and ends in the anus. Along with segmentation or mixing of food, peristalsis is an essential part of providing the body with nutrients.
