These veins empty into the hypogastric veins of the body. The vaginal artery plexus communicates with the vesicle, hemorrhoidal plexuses, and the uterine plexuses. This artery extends midway into a midline vaginal artery in the posterior and anterior walls of the vagina. Vaginal artery flow naturally moves laterally, starting from the cardinal ligaments and passing through the paravaginal suspensory ligaments on the way to the vagina. Four plexuses are in charge of emptying the pelvic organs. These include the vesical venous plexus, the uterine venous plexus, the rectal venous plexus, and the vaginal artery plexus, also known as the vaginal venous plexus. The vaginal artery plexus is part of the cardiovascular system, and passes through the floor of the pelvis, draining into the internal iliac vein.
