Question

Assertion : 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.

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

Hint:

Remember: \textit{Peristalsis = rhythmic muscle movement of the gut}. If the reason mentions smooth muscle contractions pushing food forward, it correctly explains peristalsis.

Answer 1

The Correct Option is A

Explanation:

• Peristalsis is the rhythmic contraction and relaxation of muscles that pushes 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.

Conclusion: Both the assertion and reason are true, and the reason correctly explains the assertion.
