Cardiovascular System: Heart Valve Disease

223 Words1 Page
Heart Valve disease is when you heart valves dont work the way they should. This is part of the cardiovascular system. Your heart valves lie at the exit of each of your four heart chambers and maintain one-way blood flow through your heart. The four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage. Blood flows from your right and left atria into your ventricles through the open tricuspid and mitral valves. When the ventricles are full, the tricuspid and mitral valves shut which prevents blood from flowing back into the atria while the ventricles contract. As the ventricles begin to contract, the pulmonic and aortic valves are forced open and blood is pumped out of the ventricles.
