Use a flowchart to show the progression from Trachea → Main Bronchus → Lobar Bronchus → .

: Every segment is functionally separate, meaning infections or tumors can often be localized to a single segment. Bronchopulmonary Segments Ppt

5 potential segments but often 4 due to S7+S8 fusion. Use a flowchart to show the progression from

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 The left lung typically has two lobes; some

Before and after CT scans showing a wedge resection vs. a segmentectomy.

The right lung has three lobes and . This slide should feature a labeled diagram of the right lung.

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.
