Question

In which part of the gut does physical digestion takes place?
​

Answer 1

Answer:

The stomach walls contain three layers of smooth muscle arranged in longitudinal, circular, and oblique (diagonal) rows. These muscles allow the stomach to squeeze and churn the food during mechanical digestion. Powerful hydrochloric acid in the stomach helps break down the bolus into a liquid called chyme.

Answer 2

Explanation:

Mechanical digestion begins in your mouth with chewing, then moves to churning in the stomach and segmentation in the small intestine. Peristalsis is also part of mechanical digestion.
