In
human anatomy, the 'common iliac veins' are formed by the
external iliac veins and
internal iliac veins and together, in the
abdomen at about the level of the
umbilicus, form the
inferior vena cava. They drain
blood from the
pelvis and lower limbs.
Both common iliac veins are accompanied along their course by
common iliac arteries.
