[2] The single right bronchial artery usually arises from one of the following: 1) the thoracic aorta at a common trunk with the right 3rd posterior intercostal artery; 2) the ...

Image showing main pulmonary artery coursing ventrally to the aortic root and trachea. The right pulmonary artery passes dorsally to the ascending aorta, while the left pulmonary artery passes ventrally to the descending aorta. De-oxygenated blood leaves the heart, goes to the lungs, and then enters back into the heart. [2]

It is complementary to the pulmonary circulation that brings deoxygenated blood to the lungs and carries oxygenated blood away from them in order to ...

[2] In this article, Permutt suggests "The pressure in the pulmonary arteries and veins is less at the top than at the bottom of the lung. It is quite likely that there is a portion of the lung toward the ...
