Common Iliac Artery

Tuesday, May 17, 2011

The common iliac artery is either of two large arteries which arises from the end of the abdominal aorta, being a bifurcation of this blood vessel. Supplying oxygenated blood to the pelvis, the common iliac arteries run obliquely towards the sides, then they branch into the external iliac artery and internal iliac artery in each side of the pelvis. Thus, the common iliac artery, and all of its branches, exist as paired structures, that is to say, there is one on the left side and one on the right. They are about 5 cm in length in adults and more than a centimetre in diameter.
