It begins at T12 and ends at L4, where it divides into the right and left common iliac arteries.c. It enters the abdomen through the aortic opening of the diaphragm, which is located beneath the median arcuate ligament between the crura of the diaphragm at T12.d. It is accompanied through the aortic opening by the azygos vein and the thoracic duct.e. It is located on the posterior abdominal wall in the retroperitoneal space of the abdomen.f.
