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.
This blood which is in need of oxygen (so-called deoxygenated blood) is sent to your lungs to pick up oxygen and get rid of carbon dioxide. Your heart pumps all day to circulate blood around the body. On average, a red blood cell in the circulation will pass through the heart every 45 seconds. If you start to exert yourself your heart will start to pump faster to supply your working muscles with the increased amount of oxygen and nutrients they need.
