Internal iliac artery (Hypogastric artery)

The internal iliac artery (hypogastric artery) is the primary artery in the pelvic area. It is usually shorter in length than the external iliac artery. The main function of this artery is to supply blood to the pelvic region, hips, thighs, and the reproductive organs. It originates from the point where the common iliac artery divides itself, and moving downward it separates into anterior and posterior trunks. The artery lies at the back of the ureter and in front of the internal iliac vein. The obdurator nerve is positioned below it, while the external iliac vein is medial to it. The precise organization of the branches of this artery varies from one place to another. The size of the artery is nearly double the size of the external iliance within the fetus. As the internal iliac artery (hypogastric artery) rises along the bladder, it traverses across the abdominal wall to the umbilicus. Once it goes through the umbilicus, it coils around the umbilical vein, and eventually ramifies within the placenta.
