Iliac artery

In human anatomy, the iliac arteries are three arteries located in the region of the ilium in the pelvis:
 * Common iliac artery – forms at terminus of the aorta
 * External iliac artery – forms when the common iliac artery bifurcates, continues as the femoral artery at the inguinal ligament
 * Internal iliac artery – forms when the common iliac artery bifurcates, supplies the perineum and sexual organs.
