Dissection of lungs in situ
General view of vascular and bronchial distribution within lungs.
The specimen is shown in a considerably more advanced stage of dissection than that in the previous view. The upper lobes of both lungs and the right middle lobe have been removed. However, the major vessels and bronchi to these parts have been preserved. Most of the heart has been removed. The ascending aorta has been cut off to expose the right pulmonary artery (8). The pericardium has been cut away except for its posterior and diaphragmatic parts.
