View Originalfigure 1Chambers and valves of the heart
The heart has four main sections, or "chambers. " пїЅ The top two chambers are called the right atrium and left atrium. The bottom two chambers are called the right and left ventricles. Each of these chambers has a valve that keeps blood flowing in one direction. The valves in this picture appear in gray. When the heart is working normally, blood comes in from the body through the right atrium and into the right ventricle. From there it goes to the lungs, where it picks up oxygen. Then the blood comes back through the left atrium, into the left ventricle, and back out to the body through a blood vessel called the aorta. The aorta appears in red. If a valve doesnt work properly, it will either let blood flow backwards in the wrong direction or not let enough blood flow forwards.
