QuestionChoice
The image shows a dissected thoracic cavity with the lungs and the heart removed, but with the main heart vessels in situ. The brachiocephalic trunk is the first branch of the aortic arch which then divides into the right common carotid artery and the right subclavian artery. However, the arrow points to the descending aorta, which lies posterior to the ascending aorta and aortic arch.

Descending aorta
QuestionChoice
The image shows a dissected thoracic cavity with the lungs and the heart removed, but with the main heart vessels in situ. The aortic arch is the curved part of the aorta connecting the ascending and the descending parts of the aorta. The aortic arch can be recognised by its curved shape and by the three main branches that emerge from it. However, the arrow points to the descending aorta, which lies posterior to the ascending aorta and aortic arch.
