What is the role of the right side of the heart?

• A. To pump deoxygenated blood to the lungs
• B. To pump oxygenated blood to the body
• C. To receive deoxygenated blood from the body
• D. To regulate blood pressure

Answer: (A)

The right side’s job is to move deoxygenated blood from the body to the lungs for oxygenation. It collects blood that is low in oxygen from the body and routes it through to the lungs through the pulmonary circulation. In practical terms, the right atrium receives blood from the body, and the right ventricle pumps that blood to the lungs via the pulmonary arteries. This oxygenation in the lungs then returns blood—now oxygenated—to the left side to be circulated to the body. Pumping oxygenated blood to the body is the function of the left side. Receiving deoxygenated blood from the body is a part of the atrial entry process, but the overall role of the right side is to send that blood to the lungs. Regulating blood pressure is a broader function influenced by the entire heart and circulation, not a specific, primary role of the right side alone.
