Related to Bronchopulmonary segments: bronchopulmonary dysplasia
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]
The largest subdivision of a lobe of the lung, supplied by a direct branch of a lobar bronchus and separated from adjacent segments by connective tissue septa.
the area of lung supplied by a segmental bronchus and its accompanying pulmonary artery branch. Each segment is shaped like an irregular cone with the apex at the origin of the segmental bronchus and the base projected peripherally onto the surface of the lung.
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.
bronchopulmonary segmentA subdivision of a lobe of a lung based on its connection to a segmental bronchus
bron·cho·pul·mo·nar·y seg·ment(brong'kō-pul'mŏ-nār-ē seg'mĕnt)
The largest subdivision of a lobe of the lung; it is supplied by a direct tertiary (lobular) bronchus and a tertiary branch of the pulmonary artery; it is separated from adjacent segments by connective tissue septa.
pertaining to the bronchi and lungs.
congenital bronchopulmonary foregut malformation
accessory lungs which communicate with the intestine.
one of the smaller divisions of the lobe of a lung, separated from others by a connective tissue septum and supplied by its own branch of the bronchus leading to the particular lobe.
a demarcated portion of a whole.
one of the subdivisions of the lobe of a lung, sometimes separated from others by a connective tissue septum and supplied by its own branch of the bronchus leading to the particular lobe.
subdivisions of the hepatic lobes based on arterial and biliary supply and venous drainage.
