Segmental bronchi of left lung, lateral view

The left pulmonary artery (10) has been cut across at the hilum of the lung to permit the removal of its peripheral branches. The left pulmonary veins, similarly cut off at the hilum, are partially obscured by the bronchi.

1. Anterior segmental bronchus
2. Upper pointer: Left superior lobar bronchus Lower pointer: Left superior pulmonary vein (cut off)
3. Upper pointer: Superior lingular bronchus Lower pointer: Inferior lingular bronchus
4. Medial basal segmental bronchus (4. & 5. originating from a common stem in this specimen)
5. Anterior basal segmental bronchus
6. Posterior basal segmental bronchus
7. Left superior intercostal vein (covered by pleura)
8. Aortic arch (covered by pleura)
9. Apicoposterior segmental bronchus (note unusual origin of posterior ramus of posterior subsegmental bronchus from anterior segmental bronchus)
10. Upper pointer: Left pulmonary artery (cut off) Lower pointer: Left principal bronchus (emerging from mediastinum)
11. Left inferior lobar bronchus
12. Superior segmental bronchus
13. Subsuperior segmental bronchus
14. Lateral basal segmental bronchus
