The<unk> es are two large arteries, about 4cm long in adults but more than a centimetre in diameter, that originate from the aortic bifurcation and terminate when bifurcating into the external iliac artery and internal iliac artery. The<unk> , 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).
The distribution of the<unk>  is basically the pelvis and lower limb on the corresponding side.
Both<unk> es are accompanied along their course by common iliac veins.
