Your heart is really a muscle! It is located a little to the left of the middle of your chest. Believe it or not the heart even carries away waste! It also provides oxygen and nutrients you need. Your heart pumps blood into your lungs, and then the lungs pump blood into the heart. The two chambers of the heart are the right and left ventricle. A thick wall of muscle running down the middle of the heart is called the Septum. The septum's job is to separate the left and right side of your heart. The heart also has two "Valves" These are referred to as the mitral, tricuspid, aortic, and the pulmonary valve. They let blood flow from the atria to the ventricles. Your heart pumps 5 quarts of blood every minute. Your heart even beats 100,000 times A DAY! Thats about 35 million times a year!
