Question

is the involuntary movement of the muscles that move food through the digestive system.
options: peristalsis, salivation, digestion, secretion

Explanation:

To solve this, we analyze each option:

• Peristalsis: Involuntary muscle contractions that move food through the digestive tract.
• Salivation: Production of saliva, not muscle movement for food transport.
• Digestion: Breakdown of food, not the movement.
• Secretion: Release of substances (like enzymes), not muscle movement.

So the correct term is Peristalsis.

Answer:

A. Peristalsis
