Systemic circulation carries blood to and from which area?

Systemic circulation carries blood to and from which area?

• A. Heart — lungs
• B. Heart — body
• C. Brain — heart
• D. Liver — heart

Answer: (A)

Systemic circulation is the pathway that carries blood between the heart and all the body’s tissues. Oxygen-rich blood is pumped from the left ventricle into the arteries, travels to tissues throughout the body where oxygen and nutrients are delivered and waste products picked up, and then returns to the heart via veins into the right atrium. The lungs are served by a separate loop called the pulmonary circulation, which handles gas exchange in the lungs and returns blood to the heart. So the area involved in systemic circulation is the body as a whole, not the lungs.
