The heart is a hollow muscle comprised of four chambers surrounded by thick walls of tissue (septum). The atria are the two upper chambers, and the ventricles are the two lower chambers.
The left and right halves of the heart work together to pump blood throughout the body. The right atrium (RA) and the right ventricle (RV) pump deoxygenated blood to the lungs, where it becomes oxygenated. This oxygen-rich blood returns to the left atrium (LA) and enters the left ventricle (LV). The LV is the main pump that delivers the newly oxygenated blood to the rest of the body.
