Question

What happen if direction of peristalsis is reversed

Answer 1

Explanation:

Retroperistalsis is the reverse of the involuntary smooth muscle contractions of peristalsis. It usuallyoccurs as a precursor to vomiting. Local irritation of the stomach, such as bacteria or food poisoning, activates the emetic center of the brain which in turn signals an imminent vomiting reflex.
