Arteries have a thicker muscular layer to deal with, and help control, higher pressures inside the lumen as blood is pumped through them by the heart. And veins, have valves that help them move blood back toward the heart.
function of capillaries in leaf
The function of the capillaries in the circulatory system is to allow diffusion of wastes, oxygen, and nutrients to the tissues. The rest of the circulatory system is designed to move the blood to the capillaries so they can perform this function.
presence of many capillaries
The structure of the malpighian body includes a network of capillaries surrounded by Bowman's capsule. This structure is adapted for ultrafiltration due to the small pores in the capillaries that allow small molecules to pass through while blocking larger ones, and the high pressure in the capillaries that forces fluid and solutes into Bowman's capsule.

The blood vessels, which include the capillaries, function to distribute nutrients such as glucose and oxygen to the body tissues and to carry wastes such as carbon dioxide and urea away from the tissues to be excreted.
The function of blood capillaries is to provide cellular, or tissue, respiration, provide nutrients and remove waste products. They are the tiny blood vessels that are between the venules and arterioles and the interstitial space between cells.
