Correct answer: A. Left atrium
- A. Left atrium
- B. Right atrium
- C. Left ventricle
- D. Right ventricle
Explanation
After oxygenation in the lungs, the oxygenated blood is brought by pulmonary veins to the left atrium of the heart. The pulmonary veins are blood vessels that carry oxygenated blood from the lungs back to the heart. There are four pulmonary veins in total: two from the right lung and two from the left lung. The two pulmonary veins from the left lung directly enter the left atrium, while the two pulmonary veins from the right lung enter the left atrium through the right atrium.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
