Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
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.
Metabolites exchange by diffusion with tissue cells at the capillaries in the circulatory system. Capillaries are the smallest blood vessels where the exchange of nutrients, oxygen, and waste products occurs between the blood and the surrounding tissue cells.
Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.
To allow Oxygen to travel to every Cell in a living organism there is a gas exchange between nearby Capillaries and the cells of that organism.The same exchange works the other direction to take away waste products of cell living
