<prompt> TRUE statement about bronchopulmonary segmentSpherical in shapeAery is intersegmentalPulmonary veins are intersegmentalNon resectable  <response>: 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.
