Which chamber of the heart receives oxygenated blood from the pulmonary veins?
Correct answer: C. Left atrium
- A. Right atrium
- B. Right ventricle
- C. Left atrium
- D. Left ventricle
Explanation
The left atrium receives oxygenated blood from the four pulmonary veins and passes it through the mitral valve to the left ventricle. The right atrium receives deoxygenated blood from the venae cavae, so it is a common distractor.

The cardiovascular system covers the chambers, valves and major vessels of the heart, the cardiac cycle, conduction pathway, blood pressure and the circulation through pulmonary and systemic circuits. It also explains artery, vein and capillary structure, exchange at capillary beds, and how the cardiac cycle differs from general blood flow.
