The right upper lobe (10) and middle lobe (19) have been pulled across the midline of the body to demonstrate the hilar region of the lower lobe and to display the interlobar parts of the pulmonary vessels. Small areas of fusion between the upper and lower lobes (1), and between the middle and lower lobes (3), have been divided in order to separate the lobes. The bronchopulmonary lymphatic vessels and nodes of the lower lobe have been preserved.
