Where does the heart pump the oxygenated blood?

• A. From the lungs to the body.
• B. From the body to the lungs.
• C. Within the heart only.
• D. From the arteries to the veins.

Answer: (A)

The heart moves oxygen-rich blood to the rest of the body. Oxygenated blood comes from the lungs and reaches the heart, where it is pumped out into the body through the arteries to supply tissues with oxygen. Then the blood returns deoxygenated to the heart to be sent again to the lungs for gas exchange. This means the heart effectively transfers oxygenated blood from the lungs to the body, which is why this option is correct. The other statements describe different parts of circulation (deoxygenated blood moving to the lungs, staying inside the heart, or the general direction of blood in vessels) and don’t specify the heart’s role in delivering oxygenated blood to the body.
