The left upper lobe of the lung has a superior division, which consists of the apical-posterior segment and the anterior segment, and an inferior (lingular) division, which contains the superior and inferior segments. Branches of arteries and veins that stem from the thoracic branch supply the lobes of the left lung, and these, in turn, stem from the descending aorta.
