What is the pressure range generally associated with pulmonary circulation?

• A. 5-10 mmHg
• B. 10-20 mmHg
• C. 20-30 mmHg
• D. 30-40 mmHg

Answer: (B)

The pressure range generally associated with pulmonary circulation is indeed in the range of 10-20 mmHg. This low-pressure system is essential for proper gas exchange in the lungs. The pulmonary arteries carry deoxygenated blood from the right heart to the lungs, where it can pick up oxygen and release carbon dioxide. In comparison to systemic circulation, which operates under much higher pressures (typically around 70-100 mmHg), the pulmonary circulation pressure must remain lower to prevent damage to the delicate structures of the lungs, such as the alveoli. High pressures in the pulmonary vasculature can lead to complications such as pulmonary hypertension, which can significantly impact respiratory function and overall cardiovascular health. By maintaining a pressure range of 10-20 mmHg, the pulmonary circulation is optimized for efficient gas exchange while minimizing the risk of injury to lung tissue from overly high pressures.
