The right atrium contracts and pumps the blood through the tricuspid valve and into the right ventricle, which then pumps the blood through the pulmonary artery into the lungs. In here, tiny blood vessels called capillaries absorb carbon dioxide from the lungs and replace it with oxygen. The oxygenated blood flows through the pulmonary vein and into the left atrium. The oxygenated blood pumps through the mitral valve and into the left ventricle. The left side of the heart contracts the strongest to send blood out of the left ventricle and through the aortic arch on its way to the body.If the left ventricle loses its contractility what happens and why?
