1. Illustration of the main anatomic features of the bronchial circulation. Note that the bronchial circulation supplies blood flow to the tracheobronchial tree down to the level of the terminal bronchioles as well as to the pulmonary blood vessels, the visceral pleura, the hilar lymph nodes, and branches of nerves, including the vagus. A bronchopulmonary anastomosis is shown at right and is enlarged in the inset. Venous drainage is to both the right side of the circulation via the azygos (and hemiazygos) vein and the left side of the circulation via the pulmonary veins.
