Bronchopulmonary Segments: Anatomical Division of the Lungs
Introduction
The bronchopulmonary segments are the fundamental structural and functional units of the lungs. Each lung contains multiple segments, which are independently supplied by segmental bronchi and arteries.
Structure and Organization
Right Lung Segments
- Upper Lobe:
- Apical
- Posterior
- Anterior
- Middle Lobe:
- Lateral
- Medial
- Lower Lobe:
- Superior
- Medial Basal
- Anterior Basal
- Lateral Basal
- Posterior Basal
Left Lung Segments
- Upper Lobe:
- Apicoposterior
- Anterior
- Lingula:
- Superior
- Inferior
- Lower Lobe:
- Superior
- Medial Basal
- Anterior Basal
- Lateral Basal
- Posterior Basal
Clinical Significance
Each bronchopulmonary segment can function independently, which is crucial for surgical interventions like segmentectomy. Additionally, infections and pathological conditions can be localized within a single segment.
Conclusion
Understanding bronchopulmonary segments aids in precise diagnosis, treatment planning, and surgical procedures involving the lungs.
