A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.
Capillaries are found in every square inch of the body, from the skin to the deepest tissues in the body's cavities. There are between 60,000 to 100,000 miles of blood vessels stretching throughout the human body, depending on the size and weight of the person, and most of these are capillaries.
