The female genitalia, also known as the vagina, is a sexually dimorphic biological structure that forms part of the reproductive system in humans and other mammals.

The vagina has numerous functions, including facilitating sexual intercourse, childbirth, and providing pleasure. The vagina is a muscular canal that extends from the vaginal opening to the cervix.

The walls of the vagina are lined with different types of epithelium, which is a soft tissue that protects the body from infection. The inside of the vagina has many ridges, or folded areas, that help to increase surface area.

The vulva is the external portion of the female genitalia, which includes the clitoris, labia minora and major, and the vaginal opening.
