A: The function of the arteries is to carry oxygenated blood to organs and cells in the body. Because of this, arterial blood has a bright red color and flows away from the heart.

Blood Vessel Structure and Function-. A. Overview- Great arteries leave the heart, branch to smaller and. smaller arteries which lead to capillaries. Capillaries allow exchange of. materials at tissues.
