Question

ASSERTION (A): Capillaries are the thinnest blood vessels. REASON (R):Capillaries connect the branches of arteries and veins.

Answer 1

Both the assertion and the reason are correct but the reason is not for this assertion.

Explanation:

• Capillaries can be described as the thinnest blood vessels in the body of an organism.
• The reason for capillaries to be the thinnest blood vessels is because capillaries have to exchange gases as well as nutrients between the blood and the body tissue. For example, in the lungs, capillaries take in oxygenated blood from the lungs and give away the de-oxygenated blood back to the lungs.
