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 or rooms.. 1  The atria (AY-tree-uh) are the two upper chambers that collect blood as it flows into the heart. 2  The ventricles (VEN-trih-kuhls) are the two lower chambers that pump blood out of the heart to the lungs or other parts of the body.
