The part of the descending aorta that extends from the diaphragm to the division into the two common iliac arteries.

abdominal aorta

the portion of the descending aorta that passes through the diaphragm into the abdomen, descending ventral to the vertebral column and ending at the fourth lumbar vertebra, where it divides into the two common iliac arteries. It supplies blood to abdominal structures such as the testes, ovaries, kidneys, and stomach. Its branches are the celiac, superior mesenteric, inferior mesenteric, middle suprarenal, renal, testicular, ovarian, inferior phrenic, lumbar, middle sacral, and common iliac arteries. See also descending aorta. Compare thoracic aorta.

abdominal aorta

The portion of the aorta that begins below the diaphragm, extends to the bifurcation of the iliac arteries and supplies blood to the abdominal viscera, pelvic organs and legs.
 
Branches
