Detailed explanation-1: -Capillaries are delicate blood vessels that exist throughout your body. 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-2: -The blood capillary walls are generally comprised of four layers, namely plasmaendothelial interface, endothelium, basal lamina, and adventia. The endothelium is a monolayer of metabolically active cells, which mediate and monitor the bidirectional exchange of fluid between the plasma and the interstitial fluid.
