PATHOLOGY

Detailed explanation-1: -Capillaries are tiny, extremely thin-walled vessels that act as a bridge between arteries (which carry blood away from the heart) and veins (which carry blood back to the heart).

Detailed explanation-2: -Capillaries are the thinnest blood vessels in the body. Capillaries help in gaseous exchanges between the tissue and blood.

Detailed explanation-3: -The walls of capillaries are extremely thin. This property allows nutrients and oxygen to travel through the bloodstream and diffuse into the tissues. As a result, waste materials can diffuse out of tissues into the bloodstream and be carried to the lungs, where they can be re-oxygenated.
