The tooth roots (pulp, dentin, endodont) are living tissue and have capillaries as well as nerves. The outer enamel consists of tubes of dead material in which the nerves gradually die off as it grows outward, toward the surface of the tooth. The remaining nerves become evident when teeth are drilled, as in the repair of cavities.

Capillaries.
The alveoli are surrounded by capillaries that carry carbon dioxide laden blood from the body and return oxygenated blood back to the body.
Capillaries are the smallest blood vessels.
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
A modified dentin permeated by blood capillaries and common in the teeth of the lower vertebrates.

Capillaries are the structures that connect arteries to veins.
Capillaries The smallest of the blood vessels: capillaries.
Arteries "feed" the capillaries while veins drain the capillaries.
plmonary veins begin as capillaries and end as capillaries
Sinusoidal Capillaries
The thin walled blood vessels are called capillaries.

Capillaries connect small arteries to small veins. Capillaries are the site of gas exchange.
