ANATOMY

Detailed explanation-1: -Capillaries are the thinnest blood vessels in the body. Capillaries help in gaseous exchanges between the tissue and blood.

Detailed explanation-2: -Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).

Detailed explanation-3: -Due to the thick walls of arteries and veins, blood molecules or cells cannot permeate into bodily cavities. Thus, The walls of capillaries are the thinnest.

Detailed explanation-4: -They transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system.

Detailed explanation-5: -The smallest type of blood vessel. A capillary connects an arteriole (small artery) to a venule (small vein) to form a network of blood vessels in almost all parts of the body. The wall of a capillary is thin and leaky, and capillaries are involved in the exchange of fluids and gases between tissues and the blood.
