Diagrams The diagram below shows the placement of the vagina in the vulva, visible externally. The diagram below shows the inside of the vagina, and how it connects to the uterus. Female anatomy includes the internal and external reproductive organs. Labeled diagrams help explain the main structures and functions of the body. The vagina is an elastic, muscular tube connecting the cervix of the uterus to the vulva and exterior of the body. The vagina is located in the pelvic body cavity posterior to the urinary bladder and anterior to the rectum. The vagina is a fibromuscular tube with anterior and posterior walls – these are normally collapsed and thus in contact with one another. The shape of the vagina is not a round tunnel.
