Vagina female reproductive system
The vagina is a fibro-muscular tubular tract leading from the uterus to the exterior of the body in female mammals, or to the cloaca in female birds and some reptiles. Female insects and other invertebrates also have a vagina, which is the terminal part of the oviduct. The vagina is the place where semen from the male penis is deposited into the female's body at the climax of sexual intercourse, a phenomenon commonly known as ejaculation. The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body. It also is known as the birth canal.
