Pulmonary Circulation

Pulmonary circulation is the half portion of the cardiovascular system which carries oxygen-depleted blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The term pulmonary circulation is readily paired and contrasted with the systemic circulation. A separate system known as the bronchial circulation supplies blood to the tissue of the larger airways of the lung.

    We did not heed the sentries at the gate, nor did they us, and what under the sun they were placed there for, unless to hinder a free circulation of the air, was not apparent.
