It contains the thickest layer of myocardium and that means it can create the highest hydrostatic pressure. And that is important because it's this ventricle that is responsible for moving all that blood into the order and all the different organs and tissues and cells of our body. So we have the right atrium, the right ventricle that make up the right pump of the heart. And we have the left atrium and the left ventricle that make up the left pump of our heart. And these pumps work at the same exact time. And that means when the right pump contracts, the left pump contracts at the same time.
