Which heart chamber pumps blood to the lungs?

• A. Right Ventricle
• B. Left Atrium
• C. Right Atrium
• D. Left Ventricle

Answer: (A)

The chamber that sends blood to the lungs is the right ventricle. It pumps deoxygenated blood into the pulmonary circulation via the pulmonary trunk and arteries, delivering it to the lungs for oxygen picking and carbon dioxide removal. Once the blood is oxygenated, it returns to the heart through the pulmonary veins into the left atrium, and then moves into the left ventricle to be pumped out to the rest of the body. This distinction also reflects the two-pump system: the right side handles low-pressure pulmonary circulation, while the left side handles high-pressure systemic circulation.
