Arteries are the large vessels that
carry oxygenated blood away from the heart. The distribution of the
systemic arteries is like a ramified tree, the common trunk of which,
formed by the aorta, commences at the left ventricle, while the smallest
ramifications extend to the peripheral parts of the body and the
contained organs (see the image below).
Arterial supply, anterior view. The
arteries, in their distribution, communicate with one another (forming
what are called anastomoses) and end in minute vessels, called
arterioles, which in their turn open into a close-meshed network of
microscopic vessels, termed capillaries, the true deliverers of oxygen
and nutrients to the cells.
Arteries are found in all parts of the body, except in the hairs, nails, epidermis, cartilages, and cornea. The larger trunks usually occupy the most protected situations; in the limbs, they run along the flexor surface, where they are less exposed to injury.
