Solution:

The human heart is a muscular pumping organ the size of which can be compared to that of a fist. The heart has four chambers:

1. Right Atrium: Receives deoxygenated blood from the veins and pumps into the right ventricle.

2. Right Ventricle: Receives blood from the right atrium and pumps the blood to the lungs.

3. Left Atrium: Receives oxygenated blood from the lungs and pumps it into the left ventricle.

4. Left Ventricle: Receives blood from the left atrium and pumps the oxygenated blood to all parts of the body.
