Dissection of lungs in situ
General view of vascular and bronchial distribution within lungs.
The lungs have been dissected from their medial surfaces and are reflected laterally for this photograph. Fragmentary portions of all of the chambers of the heart have been preserved. The great vessels have been kept intact, although the aorta (8) and pulmonary trunk (27) have been elevated to expose more posterior parts of the heart.

7 . Ramus anterior right pulmonary artery
8 . Ascending aorta (pointer on aortic valve)
9 . Bronchus of right middle lobe
10 . Right inferior pulmonary vein (at entrance into left atrium)
11 . Right atrium
