bron·cho·pul·mo·nar·y seg·'ment

[TA]
smallest surgically resectable subdivision of the lobes of the lungs, supplied exclusively by a tertiary (segmental) bronchus and the corresponding tertiary branch of the pulmonary artery (segmental pulmonary artery); typically, the right lung has ten bronchopulmonary segments, and the left has eight or nine due to a merging of the apical and posterior segments of the upper lobe and of the anterior and medial basal segments of the lower lobe.
Synonym(s): segmentum bronchopulmonale [TA]

bronchopulmonary segment

A subdivision of a lobe of a lung based on its connection to a segmental bronchus; it is separated from the surrounding lung by a layer of connective tissue, which allows relatively facile resection when a pathology is confined to that segment.
