The uterine vein refers to a group of blood vessels found near the genitalia on the female human body. These veins are considered part of a network of blood vessels called the uterine venous plexus. The uterine vein facilitates the flow of blood within the plexus. The uterine plexus and uterine vein emerge from the sides of the female reproductive sex organ known as the uterus. These veins lie in close proximity to the vagina. The functional purpose of the uterine veins and plexus is to help deliver blood flow from the uterus to the heart. Once the blood has circulated through the uterine plexus, it leaves the uterus by draining through the uterine veins. There are two uterine veins, one on either side of the uterus near the bottom of the plexus. The veins then converge with the hypogastric vein. The uterine vein connects with the ovarian vein. The vaginal veins the stem from the vaginal venous plexus can drain into the uterine vein. The blood vessel may be susceptible to uterine vein thrombosis, a medical condition in which a blood clot develops within a blood vessel and obstructs the flow of blood.
