Segmental bronchi of right lung, lateral view
The branches of the right pulmonary artery have been cut away from the specimen shown in the previous photograph to expose the segmental divisions of the right bronchus. The upper lobar bronchus (2) divides into apical, posterior and anterior segmental bronchi (1, 11). The middle lobar bronchus (13) divides into lateral and medial segmental bronchi (15). The inferior lobar bronchus (4) gives off a superior segmental bronchus (3) and continues downward to divide into four basal segmental bronchi (4, 6, 7, 8). In this specimen it is apparent that the lateral ramus (5) of the anterior basal segmental bronchus has a high origin from the lobar bronchus.
