Each of the tertiary bronchi serves a specific bronchopulmonary segment. These segments each have their own artery. Thus, each bronchopulmonary segment is supplied by a bronchus, and an artery.

There are 10 bronchopulmonary segments on Right Lobe lung (3 in right superior lobe, 2 in middle right lobe, 5 in right inferior lobe) and 9 bronchopulmonary segments on Left Lobe( 4 in left superior lobe, 5 in left inferior lobe). Each of which is separated from the others by a layer of connective tissue.

This means that each bronchopulmonary segment is a discrete anatomical and functional unit, and this separation mean that a bronchopulmonary segment can be surgically removed without affecting the function of the other segments.
