The veins responsible for returning blood to the heart are the Superior and Inferior Vena Cava. Arteries send blood away from the heart, going from Arteries to Arterioles to Câ¦apillaries, then the return is from Capillaries to Venules to Veins. The Superior and Inferior Vena Cava are the veins that send blood to the right atrium after an entire blood circulation cycle.
The heart valves function like one-way doors which allow blood flow through in the forward direction but prevent the backward flow of blood. Venous blood returns from the body to the right side of the heart which pumps the blood to the lungs. The oxygen-rich blood returns from the lungs to the left side of the heart. The left side of the heart pumps blood to the entire body. As you would expect, the left side of the heart must generate a much greater pressure to pump the blood to the body. On the left side the valves are called mitral and aortic valves.
