Question

Assertion (A): The peristaltic movements occur all along the gut.

Reason (R): The lining of the gut has muscles that contract rhythmically to push the food in regulated manner.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Explanation:

Peristalsis is the rhythmic contraction and relaxation of muscles that push food along the digestive tract. This movement occurs throughout the alimentary canal (gut). The gut lining contains smooth muscles that contract rhythmically to move food forward. Hence , both the assertion and reason are true, and the reason correctly explains the assertion.
