Bronchopulmonary Segments Ppt [exclusive] -

For medical students, radiology residents, thoracic surgeons, and pulmonologists, understanding the bronchopulmonary segments is not merely an anatomical exercise—it is a clinical necessity. These segments represent the functional units of the lung, each acting as an independent territory with its own segmental bronchus and tertiary branch of the pulmonary artery.

The left lung typically has two lobes; some segments often fuse: Superior Lobe (4-5 segments) Apicoposterior (S I + S II) — often combined. Anterior (S III) Superior Lingular (S IV) Inferior Lingular (S V) Inferior Lobe (4-5 segments) Superior (S VI) Anteromedial Basal (S VII + S VIII) — often combined. Lateral Basal (S IX) Posterior Basal (S X) Slide 5: Vascular Anatomy Arterial Supply : Each segment is supplied by a dedicated branch of the pulmonary artery that runs centrally alongside the bronchus. Venous Drainage : Unlike the arteries, pulmonary veins Bronchopulmonary Segments Ppt
