The upper chambers, called the left and right atria, and the lower chambers, which are called the left and right ventricles. Oxygenated (o2) blood leaves the heart from the left ventricle entering the ascending aorta where the right and left coronary arteries branch off. Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill.

The upper chambers, called the left and right atria, and the lower chambers, which are called the left and right ventricles. (note:they are the only veins that carry oxygenated blood.) and the blood is poured into the left atrium from which it passes through the bicuspid valve or the mitral valve into the left ventricle. Blood rich in oxygen leaves your lungs and enters your left atrium via the pulmonary veins. There are four heart valves within the heart:
