• C. 4
• D. 5

Answer: (C)

The human heart consists of four chambers, which include two atria and two ventricles. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which then sends the blood to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and transfers it to the left ventricle, which then pumps the oxygen-rich blood to the rest of the body. This four-chamber structure is crucial for the effective separation of oxygenated and deoxygenated blood, enabling a more efficient circulation system. This design supports the heart's role in maintaining oxygen levels in the blood and ensuring that tissues receive the oxygen they need for proper function. Understanding this anatomy is vital for accurate interpretation of EKGs, as any issues related to heart chambers can affect cardiac rhythm and overall heart function.
