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.
The same. The left ventricle feeds the blood to the lungs then to the right ventricle. If the right pumped more blood then the left, there would be a build up of negative pressure.Not a good thing. Although, the right ventricle does push the blood at a strong pressure, but that is unrelated to the question. healthy heart would pump more blood out of it's left ventricle because that part of the heart pumps blood to the WHOLE body. The right ventricle only has to pump blood to the lungs, and therefore doesn't need as much force as the left side of the heart.
