The Pulmonary Circulation Does Not Directly Serve the Metabolic Needs

Question

The pulmonary circulation does not directly serve the metabolic needs of body tissues.

Accepted Answer

The pulmonary circulation is responsible for transporting deoxygenated blood from the heart to the lungs for oxygenation and then returning oxygenated blood back to the heart. It does not directly supply oxygen or nutrients to the body tissues. That is the job of the systemic circulation.
