Dissection of lungs in situ

Left lung.

Branches of the pulmonary artery and vein have been removed to demonstrate the segmental bronchi (12, 13, 16, 19, 20, 22) of the lower lobe. The view is directed medially.

1 .	Pulmonary trunk
2 .	Left main bronchus
3 .	Upper pointer: Superior lingular bronchus (in foreground) Lower pointer: Inferior lingular bronchus (in foreground)
4 .	Left inferior pulmonary vein
5 .	Posterior mediastinal lymph node
6 .	Pericardium
7 .	Pulmonary ligament
8 .	Left pulmonary artery (cut off)
9 .	Posterior apical segmental bronchus
10 .	Interlobar surface lower lobe
11 .	Anterior segmental bronchus
12 .	Superior segmental bronchus (pointer on superior branch)
13 .	Superior segmental bronchus (pointer on lateral branch)
14 .	Posterior and lateral basilar branches left pulmonary artery
15 .	Upper pointer: Left lower lobe bronchus Lower pointer: Bronchial branch of aorta
16 .	Anterior basal segmental bronchus
17 .	Lateral branch of no. 16
18 .	Basal branch of no.16
19 .	Medial basal segmental bronchus
20 .	Lateral basal segmental bronchus
21 .	Upper pointer: Anteromedial branch of no. 19 Lower pointer: Anterolateral branch of no. 19
22 .	Posterior basal segmental bronchus (division of this bronchus into laterobasal and mediobasal branches is visible below pointer)
