Question

Quizplus · Accepted Answer

The descending aorta is the correct choice as it is divided by the diaphragm into a thoracic portion and an abdominal portion. The aortic arch (A) is located superiorly to the diaphragm and is not divided into portions by the diaphragm. The ascending aorta (B) is also located superiorly to the diaphragm and does not pass through it. The superior mesenteric artery (D) and celiac artery (E) are not vessels of the great vessel system.
