Concerning the Tracheobronchial tree1 a bronchopulmonary segment refers to a portion of lung supplied by a

segmental bronchus and accompanying segmental branch of the pulmonary artery

2 the upper lobe bronchus of the right lung gives rise to four segmental bronchi

3 the lower lobe bronchus of the left lung gives rise to three segmental bronchi

4 the lower lobe bronchus of the right lung gives rise to five segmental bronchi

5 in the recumbent individual the most dependent bronchopulmonary segment is the apical segment of the upper lobe
