The vagina constitutes the part of the female reproductive tract between the [[Female_Reproductive_Tract_-The_Cervix_- Anatomy & Physiology|cervix]] and the vulva.  With the vestibule and vulva, it is the copulatory organ and the birth canal.  The '''hymen''' is the poorly developed, vestigial, mucosal folds at the junction of the vagina and vestibule.
