Respuesta :

Answer:

The correct option is: B) peristalsis

Explanation:

Peristalsis is the involuntary wave-like contractions and relaxations of the smooth muscles of the gastrointestinal tract of the humans.

These alternating contractions and relaxations produces a peristaltic wave that pushes the food down the esophagus of the digestive system. The peristaltic movement prevents the food from moving backwards and pushes the food forward.
