The abdominal aorta

The main branches of the abdominal aorta are:

  • the coeliac artery, the superior mesenteric artery and the inferior mesenteric artery, which supply the gut
  • the renal arteries to the kidneys.


The abdominal aorta also divides into two common iliac arteries. Each of these branches into:

  • an internal iliac artery that supplies the pelvic organs
  • an external iliac artery that becomes the femoral artery to the legs (running alongside the femur).
