How Our Circulatory System Works

Our circulatory system consists of our heart and blood vessels.

Blood supplies the tissues with oxygen and nutrients.

Arteries carry blood away from the heart

Veins return blood to the heart

The American Medical Association atlas of the circulatory system outlines the different parts of the body in this system, including:

Circulation - General

Circulation - Arterial

Circulation - Venous
