A difference between female rats and humans is that a rat's vagina connects to the urogenital aperture and humans do not have a urogenital aperture. The vagina is a short, muscular canal located below the urethra. Additionally, the rat's vagina is much shorter in length than the human vagina. In female rats, the ovaries which produces egg cells and female hormones, are small and located just below the kidneys inside the peritoneal membrane.
