Step 2 : Answer to the question "How many chambers are there in a normal human heart?"
4:
The human heart's structure has four distinct chambers, two on the left and two on the right. The atria are the two upper chambers and the ventricles are the two lowers. Each chamber is coordinated with its counterpart, receiving and pumping blood in a tireless cardiovascular cycle that moves blood throughout our bodies. The right side of the heart receives blood filled with carbon dioxide from the body and sends it to the lungs to trade the CO2 for a fresh supply of oxygen. The oxygen-rich blood returns to the left side of the heart, where it is then pumped out to the body. Source: Reference.com
