Final answer:
A bronchopulmonary segment is a section of a lung lobe with its own airway and blood supply, and the right lung has 10 while the left lung has 8-10 of these segments.
Step-by-step explanation:
A bronchopulmonary segment is a distinct anatomical and functional unit within the lungs, each of which receives air from its own tertiary bronchus and blood from its own artery. There are typically 10 bronchopulmonary segments in the right lung and 8 to 10 in the left lung, varying slightly due to anatomical differences and presence of the heart on the left side leading to fewer segments in the superior lobe.
These segments are clinically significant because diseases can affect them individually, and they can be surgically removed with minimal effect on adjacent segments. The lungs have different numbers of bronchopulmonary segments on each side. The right lung has 10 bronchopulmonary segments, and the left lung has 8 or 9 bronchopulmonary segments.
