Capillary is one of the classifications of blood vessels. Among the three classifications of blood vessels, it is the smallest and most numerous. It forms the connection between arteries (vessels that carry blood away from the heart) and veins (vessels that return blood to the heart). Its primary function involves the exchange of materials between the blood and tissue cells.

The distribution of capillaries in our body varies with the metabolic activity of body tissues. Tissues like skeletal muscle, liver, and kidneys are metabolically active and require an abundant supply of oxygen and nutrients, thus having extensive capillary networks. Other tissues, like the connective tissue, have a less abundant supply of capillaries. Moreover, the epidermis of the skin and lens and cornea of the eye completely lack a capillary network.
