Question

Human circulatory pathways

Answer

◇Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body.

◇From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.

◇The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body.

◇It consists of the heart and the blood vessels running through the entire body.

◇The arteries carry blood away from the heart; the veins carry it back to the heart.
