TRUE statement about bronchopulmonary segment
Bronchopulmonary segment: segment of lung which is aerated by teiary bronchus and its accompanying pulmonary aery branch. A bronchopulmonary segment is the smallest functionally independent region of a lung &the smallest area of lung that can be isolated & removed without affecting adjacent regions. Right lung: 10 bronchopulmonary segment (BPS) and left lung: 9 BPS. BPS is pyramidal in shape with the apex towards hilum & base towards periphery. Teiary bronchus, bronchial aery and pulmonary aery are the structures that are inside the BPS. The pulmonary veins are intersegmental in nature, not inside BPS.
