In pulmonary circulation, blood flows through two organs, the...
- A.
Lungs and heart
- B.
Heart and liver
- C.
Brain and heart
- D.
Heart and kidneys
Correct Answer
A. Lungs and heartExplanation
In pulmonary circulation, blood flows through two organs, the lungs and heart. This is because the lungs are responsible for oxygenating the blood and removing carbon dioxide, while the heart pumps the oxygenated blood to the rest of the body. The lungs receive deoxygenated blood from the heart through the pulmonary artery, and after oxygenation in the lungs, the blood returns to the heart through the pulmonary veins. Therefore, the correct answer is lungs and heart.Rate this question:
