Peripheral Circulation The function of blood circulation is transportation – bringing food and oxygen to the body’s cells and organs. As the heart pumps the blood, the arteries serve as highways to carry the blood away from the heart. The arteries must be open in order to keep the body’s cells alive and healthy. “Peripheral” means the arteries that run along the arms and legs.
