The walls of capillaries are very thin allowing the nutrients of cells to diffuse through them. They facilitate the diffusion of nutrients to the body by passing them through their cell walls.
they are thin i think and they can diffuse
Because their walls are very thin.
The exchange that takes place between organs and blood are **** and ********
Capillaries
the oxygenated blood flows from arteries to capillaries and after the exchange of material in capillaries and tissues it goes to vein and veins carries this deoxygenated blood to heart.
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.

Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
The human circulatory system consists of arteries, veins, and capillaries. The capillaries are the thin-walled vessels that connect arteries and veins and allow for the exchange of materials between blood and tissue fluid.
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
alveolus
capillaries
Lungs do not pump blood. They are the site of gas exchange between capillaries and alveoli.
