The blood supply of the vulva and perineum is derived fromthe external and internal pudendals (pudics). The internalpudendals pass deeply along the ischial and pubic rami givingoff numerous superficial branches in their course. Branchesfrom the internal pudendal supply the corpora cavernosa, thebulbi vestibuli, and the labia. The veins correspond to thearteries.

Under sexual ex-citement, and during menstruation orpregnancy, the amount of this secretionis largely increased. The hypogastric, the uterine, thevesical, and the pudendal arteries all send branches to the vagina.The pulsations of the uterine artery may sometimes be felt throughthe upper part of the vaginal walls.
