Question

Through which blood vessel does blood not flow on its way from the aortic arch to the kidney?
A) Thoracic aorta
B) Descending aorta
C) Ascending aorta
D) Renal artery

Accepted Answer

Blood flows from the aortic arch, into the descending aorta, and then into the renal arteries which supply blood to the kidneys. The ascending aorta is above the aortic arch, and therefore blood does not flow from it towards the kidneys.
