Which organ works with the lungs to pump oxygen-rich blood throughout the body?

• A. Liver
• B. Heart
• C. Lungs
• D. Stomach

Answer: (B)

How oxygenated blood is moved around the body and which organ acts as the pump. The lungs oxygenate the blood, but they don’t push it through the entire body. The organ that does the pumping is the heart. It functions as a muscular pump: the right side sends deoxygenated blood to the lungs to pick up oxygen, then the left side receives that oxygen-rich blood and pushes it out to the rest of the body through the arteries. This coordination ensures every tissue gets the oxygen it needs for energy. The liver and stomach don’t pump blood and aren’t involved in circulating oxygen-rich blood, and the lungs themselves aren’t the circulating pump.
