Artery: External iliac artery

Bifurcation of the aorta and the right iliac arteries - side view. (External iliac artery is artery at upper left, seen splitting from common iliac artery at top.)

The relations of the femoral and abdominal inguinal rings, seen from within the abdomen. Right side. (External iliac artery is large artery at center, and inguinal ligament runs from upper right to lower left. When the artery crosses the ligament, it becomes the femoral artery.)
Latin	arteria iliaca externa

The external iliac artery is a large artery in the pelvic region that carries blood to the lower limb. The external iliac artery is a paired artery, meaning there is one on each side of the body: a right external iliac artery and left external iliac artery. The external iliac artery is accompanied by the external iliac vein, which is located posterior to the artery.

Front of abdomen, showing common iliac artery, the source of the external iliac artery

The external iliac artery arises from the bifurcation of the common iliac artery. It travels inferiorly, anteriorly, and laterally, making its ways to the lower limb:

Branches

Branch	Description
Inferior epigastric artery	Goes upward to anastomose with superior epigastric artery (a branch of internal thoracic artery).
Deep circumflex iliac artery	Goes laterally, travelling along the iliac crest of the pelvic bone.
femoral artery	Terminal branch. When the external iliac artery passes posterior to the inguinal ligament, its name changes to femoral artery.
