Dissection of lungs in situ Right lung. The dissection has been carried more deeply into the lung. Various branches of the pulmonary vessels have been divided or partially removed to permit better visualization of the bronchial distribution. 1 . Branches of apical branch right pulmonary artery (cut off refer to no. in previous view) 2 . Apical segmental bronchus (note division above pointer into apical and anterior branches) 3 . Anterior segmental bronchus (note division near pointer into anterior and posterior branches) 4 . Anterior branch right pulmonary artery (cut off refer to no. 5 in previous view) 5 . Intersegmental vein 6 . Lateral segmental bronchus middle lobe (anterior branch) 7 . Medial segmental bronchus of middle lobe (note division into superior and inferior branches) 8 . Vein of middle lobe (note division into medial and lateral branches) 9 . Superior intersegmental vein 10 . Apical branches of apical branch right pulmonary artery 11 . Posterior branch right pulmonary artery 12 . Right brachiocephalic vein 13 . Left common carotid artery 14 . Right phrenic nerve 15 . Left brachiocephalic vein (cut off) 16 . Left vagus nerve 17 . Filament of pulmonary plexus 18 . Superior vena cava 19 . Right pulmonary artery (entering upper lobe) 20 . Cardiac plexus 21 . Bronchopulmonary lymph node 22 . Ascending aorta 23 .
