Pulmonary circulation refers specifically to the pathway of blood flow between the heart and the lungs. In this circuit, deoxygenated blood is transported from the right side of the heart to the lungs through the pulmonary arteries, where it receives oxygen and releases carbon dioxide. The now oxygenated blood returns to the left side of the heart via the pulmonary veins, ready to be distributed through systemic circulation to the rest of the body.

Understanding pulmonary circulation is critical in the context of cardiovascular physiology as it highlights how gas exchange occurs in the lungs, emphasizing the importance of efficient blood flow for maintaining proper oxygenation of the body's tissues.
