Veins, arteries and capillaries are the pathways in which blood is carried throughout the body.
The main structures of the circulatory system include the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood throughout the body, while arteries carry oxygen-rich blood away from the heart and veins return oxygen-depleted blood back to the heart. Capillaries are tiny blood vessels where oxygen and nutrients are exchanged with body tissues.
