Final answer:
The right side of the heart (right atrium and right ventricle) receives and pumps deoxygenated blood to the lungs, while the left side (left atrium and left ventricle) receives and pumps oxygenated blood to the rest of the body.
Step-by-step explanation:
The human heart consists of four chambers: the left and right atria, and the left and right ventricles. The right atrium and right ventricle work together to receive and pump deoxygenated blood to the lungs for reoxygenation. On the other hand, the left atrium and left ventricle receive and pump oxygenated blood to the rest of the body.
