What are capillaries?

Capillaries are the places where the exchange of substances between the blood and adjacent tissues takes place. Substance exchange can occur both between the cells that form the vessel wall and across it. Pores present in some types of blood capillaries also act as transfer sites.

Blood capillaries or capillaries as the lining of these little balls are called, are blood vessels of the circulatory system in the form of small tubes. In them, there is a large amount of carbon dioxide that diffuses into the alveolar air.
