Into which chamber do the pulmonary veins deliver oxygenated blood?

• A. Left atrium
• B. Right atrium
• C. Right ventricle
• D. Left ventricle

Answer: (A)

Pulmonary veins carry oxygen-rich blood from the lungs back to the heart and drain into the left atrium. This is the entry point for oxygenated blood after it returns from the lungs, before it moves to the left ventricle and then to the rest of the body. The right atrium and right ventricle handle deoxygenated blood returning from the body, while the left ventricle pumps oxygenated blood out to the systemic circulation. So the chamber that receives the blood from the lungs via the pulmonary veins is the left atrium.
