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 is a four-chambered, hollow organ. It is divided into the left and right side by a muscular wall called the septum. The right and left sides of the heart are further divided into: 1  two atria-top chambers, which receive blood from the veins and. 2  two ventricles-bottom chambers, which pump blood into the arteries.he heart is a four-chambered, hollow organ.
