The lungs are perfused by two circulations: the pulmonary and the bronchial. The pulmonary circulation is for oxygenation of blood. The bronchial circulation supplies blood to the lung structures (tissue). True / False.

True

Explanation:

Pulmonary circulation transports blood through the alveoli for gas exchange. In this circulation the blood that comes from the veins initially has low oxygenation, and then leaves the right ventricle of the heart through the pulmonary artery, enters the lungs and returns to the heart with arterial and oxygenated blood

The bronchial circulation is well oxygenated and provides oxygen to the lungs. The structures to which this oxygen contributes in lungs are those that do not participate in a gas exchange.
