2. How do Heart Valves Work?

In a healthy heart, blood travels from the right atrium to the left atrium (plural: atria), then enters the left ventricle through the tricuspid and mitral valves. When the ventricles are full, they close; this prevents blood from flowing back into the atria. As the ventricles contract, the aortic and pulmonary valves open, which causes the blood to rush out.
