Answer:
The aortic artery is divided into three parts: ascending aorta, aortic arch and descending aorta, the latter is divided into two parts: thoracic aorta and abdominal aorta; Depending on your location. The abdominal aorta is the most distal part of the aorta itself; It begins at the level of the diaphragm muscle, next to the lower edge of the body of T12 (the twelfth thoracic vertebra), and ends in the common iliac arteries, at the level of L4 (of the fourth lumbar vertebra) .An abdominal aortic aneurysm is a disease of the abdominal aorta.
The abdominal aorta continues the thoracic aorta at the level of the T12 vertebra, just in front of the spine and to the left of the inferior vena cava. Its path is medial, although it can take place in the right or left 1/3 of the vertebral bodies. The abdominal aorta measures between 15 and 18 cm in length and between 15 and 18 mm in caliber.
