Dissection of lungs in situ
Bronchogram, anteroposterior view
This film of a living subject was made after the bronchial tree had been partially filled with iodized oil. The air passages are distinguished in some places by their content of air (e.g. 1, 2) and elsewhere by their content of radio-opaque material either alone or in combination with air. The manner of branching of the bronchi within both lower lobes is partially obscured by overlapping shadows. Details of the bronchial distribution in these lobes are shown in the lobar dissections which follow.
1 . Conus elasticus (air-filled)
2 . Trachea (air-filled)
3 . Apical segmental bronchus of upper lobe
4 . Posterior segmental bronchus of upper lobe
5 . Anterior segmental bronchus of upper lobe
6 . Superior segmental bronchus of lower lobe
7 . Upper pointer: Lateral segmental bronchus of middle lobe Lower pointer: Medial segmental bronchus of middle lobe
8 . Left pointer: Anterior basal segmental bronchus Right pointer: Medial basal segmental bronchus
9 . Lateral basal segmental bronchus
10 . Posterior basal segmental bronchus
11 . Diaphragm
12 . Rib I
13 . Clavicle
14 . Left border of aortic arch
15 . Upper pointer: Posterior apical segmental bronchus Lower pointer: Anterior segmental bronchus
16 . Main bronchi
17 . Upper pointer: Superior lingular bronchus Lower pointer: Inferior lingular bronchus
18 . Medial basal segmental bronchus
19 . Lateral basal segmental bronchus
20 . Anterior basal segmental bronchus
21 . Upper pointer: Posterior basal segmental bronchus Lower pointer: Heart
