Which pathway correctly describes pulmonary circulation?
Correct answer: B. Right ventricle, pulmonary artery, lungs, left atrium
- A. Left ventricle, aorta, lungs, left atrium
- B. Right ventricle, pulmonary artery, lungs, left atrium
- C. Left ventricle, pulmonary artery, lungs, right atrium
- D. Right ventricle, aorta, lungs, right atrium
Explanation
The right ventricle pumps deoxygenated blood through the pulmonary artery to the lungs, where gas exchange occurs. Oxygenated blood then returns through the pulmonary veins to the left atrium.

About Cardiovascular System
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.
