Your heart handles blood in much the same way. The heart pumps about 2,000 gallons (7,571 liters) of blood a day through its chambers. Of Â­course, we're not big enough to hold that much liquid, so it just pumps the same blood over and over, and it doesn't benefit from a drop of it. At least, not initially.
Your heart is a muscular organ that pumps blood to your body. Your heart is at the center of your circulatory system.This system consists of a network of blood vessels, such as arteries, veins, and capillaries. These blood vessels carry blood to and from all areas of your body.our heart is vital to your health and nearly everything that goes on in your body. Without the heart's pumping action, blood can't move throughout your body. Your blood carries the oxygen and nutrients that your organs need to work well.
