Dissection of pericardium and heart in situ
Ascending aorta; aortic arch and branches
The branches of the aortic arch have been exposed by removing the overlying brachiocephalic vein. The superior extent of the pericardial sac in this specimen is indicated at 8. The entire ascending aorta is thus seen to lie within the pericardial cavity. The pleural coverings of the superior mediastinum have been reflected laterally on both sides to provide better exposure of the structures within the area.
