Structure
The left superior lobar bronchus arises as a branch of the left main bronchus. It passes anterolaterally to enter the hilum of the right lung, and consequently, the superior lobe of the right lung. The right superior lobar bronchus divides into superior and inferior divisions, both of which supply the superior lobe of the left lung. The superior division supplies most of the superior lobe, while the inferior division, the lingular bronchus, supplies the ligula of the left lung.
