Uterus and vagina blood supply. Illustration of the main arteries and veins serving the uterus and vagina. The uterus is at upper centre with the fallopian tubes branching either side to the ovaries (partially seen). The vagina (opening) is at bottom centre. Oxygenated blood is supplied in arteries (red) and deoxygenated blood removed by veins (blue). The cut-away blood vessels at centre left and right are branches of the uterine artery (red) and uterine vein (blue) that serve the uterus. Two sets of vaginal arteries (red, lower left and right) serve the cervix (neck of the uterus) and the vagina.
