A capillary has a small diameter, which slows the flow of blood. In addition, it has a very thin wall. Together, these structural features facilitate its function of gas and nutrient exchange with the tissues.
The key exchange between the blood and body cells are the gases involved with cellular respiration. Carbon dioxide produced by respiration is absorbed by the blood, and oxygen being carried by hemoglobin in the blood is diffused into the cells. Both of these exchanges happen due to concentration gradients.
What is the characteristic of the arteries?
Capillaries are the smallest passage in a person's body. They are one cell thick. They allow material exchange to occur.
the capillaries exchange material from tissues by the process of diffusion.
one is that there are gaps between the cells making up a capillary wall that allow materials to leave the blood and bathe the cells of the tissues.
Capillaries have extremely thin walls which allow the diffusion of oxygen and nutrients to surrounding tissues.
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
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.

capillaries
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.
