Branches of the left pulmonary artery have been cut away to reveal the more posterior subsegmental bronchi. The pulmonary plexus of nerves (5) has been more fully exposed. A branch of the bronchial artery (6) is visible.
1 . Left vagus nerve
2 . Aortic arch
3 . Upper pointer: Recurrent laryngeal nerve Lower pointer: Ligamentum arteriosum
4 . Right pointer: Left pulmonary artery Left pointer: Pulmonary trunk
5 . Pulmonary plexus (note other unlabeled nerve filaments inferiorly)
6 . Bronchial branch of aorta
7 . Left upper lobe bronchus (note division into upper and lower parts)
8 . Left superior pulmonary vein (retracted medially)
9 . Upper pointer: Superior lingular bronchus Lower pointer: Inferior lingular bronchus
10 . Pericardium (retracted medially)
11 . Upper lobe left lung
12 . Anterior branch of apical subsegmental bronchus
13 . Apical branch of apical subsegmental bronchus
14 . Upper pointer: Apical subsegmental bronchus Lower pointer: Posterior subsegmental bronchus
15 . Posterior apical segmental bronchus
16 . Anterior segmental bronchus (note posterior branch close to origin of this bronchus)
17 . Superior lingular bronchus (upper pointer, anterior branch; lower pointer, posterior branch)
18 . Intersegmental lingular veins
19 . Lower lobe left lung
