Bronchopulmonary segments of the right lung
Ten standard named right-lung territories
High-yield
Remember the grouping by lobe: 3 upper, 2 middle, 5 lower. Segment numbers identify territories rather than proving a single arterial branch per territory.
Overview
The usual right-lung segment map groups three territories in the superior lobe, two in the middle lobe and five in the inferior lobe. Branching variants occur within this familiar framework.
Reference facts
- Location
- Across the superior, middle and inferior lobes of the right lung
- Parts
- S1 apical; S2 posterior; S3 anterior; S4 lateral; S5 medial; S6 superior; S7 medial basal; S8 anterior basal; S9 lateral basal; S10 posterior basal
- Blood supply
- Segmental and variant branches of the right pulmonary artery; bronchial supply to airway walls
- Innervation
- Right pulmonary plexus
- Venous/Lymphatic drainage
- Tributaries of right pulmonary veins; lymphatic routes through pulmonary, hilar and mediastinal nodes
- Function
- Defines named ventilation and perfusion territories within the right lobes
Clinical correlation
Additional or crossing arterial branches can complicate segmental resection. Individual imaging and anatomical identification matter even when the segment names follow the usual pattern.
