Question

Assertion (A): The wall of left ventricle is thicker than the wall of right ventricle.

Reason (R): The left ventricle must generate enough force to pump oxygenated blood to the entire body, so it has thicker muscular walls compared to the right ventricle, which pumps blood to the lungs.

विकल्प

• A is True and R is False.

• A is False and R is True.

• Both A and R are True.

• Both A and R are False.

Answer 1

Both A and R are True.

Explanation:

Both statements are true. The left ventricle pumps blood throughout the body and therefore needs to generate greater force than the right ventricle, which pumps blood only to the lungs.
