Chambers and Valves. The heart is divided into four chambers: (see Figure 2). 1  right atrium (RA). 2  right ventricle (RV). 3  left atrium (LA). 4  left ventricle (LV).
The heart has four chambers that are enclosed by thick, muscular walls. It lies between the lungs and just to the left of the middle of the chest cavity. The bottom part of the heart is divided into two chambers called the right and left ventricles, which pump blood out of the heart.
