Anatomy, Classifications

The Boyden classification of bronchi refers to the standard nomenclature used to describe bronchopulmonary segmental anatomy.

Each lung has 10 segments, however, on the left, the first two segments share a common trunk and are hence B1/2. Also given the shared trunk on the left of the lower lobe anterior and medial basal segments forming the anteromedial segment, B7 is omitted.

Classification

The right lung is subdivided into three lobes with ten segments. The notation in brackets refers to the Boyden classification. The number designates the secondary lobar bronchus.
