Origin

The superior lobar arteries of the right lung are branches of the right pulmonary artery that supply the superior lobe of the right lung.

Course

As it arises from the right pulmonary artery, the superior lobar artery enters the hilum of the right lung and accompanies the right superior lobar bronchus into the superior lobe.

Branches

The superior lobar artery gives rise to three segmental arteries distally, the apical, anterior and posterior segmental arteries.

Supplied Structures

The superior lobar artery supplies the bronchopulmonary segments of the superior lobe of the right lung.
