What are bronchopulmonary segments and how do they relate to the arteries and pulmonary veins?
Understand the Problem
The question appears to require an explanation of the bronchopulmonary segments, detailing their structure, relationship to arteries, and pulmonary veins.
Answer
Segments have their own bronchus and artery; veins run between segments.
Bronchopulmonary segments are distinct functional and surgical units of the lungs, each supplied by a segmental bronchus and segmental artery. Pulmonary veins, however, do not accompany these structures, running between segments and draining multiple segments instead.
Answer for screen readers
Bronchopulmonary segments are distinct functional and surgical units of the lungs, each supplied by a segmental bronchus and segmental artery. Pulmonary veins, however, do not accompany these structures, running between segments and draining multiple segments instead.
More Information
Each bronchopulmonary segment has its own independent bronchial and arterial supply, important for surgical resection. Pulmonary veins run in intersegmental septa, not closely tied to the bronchi or arteries, aiding venous drainage across segments.
Tips
A common mistake is to think veins follow the same path as arteries and bronchi, but they actually run between the segments.
