bronchopulmonary segmentA 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.
The right upper lobe has apical, anterior and posterior segments.
