01 / Location & anatomical relationships
Inside the pelvis, between the cervix and an external opening in the vulva.
02 / Structure & organization
The vaginal wall contains a folded mucosa, smooth muscle and an outer connective-tissue layer. The cervix projects into its upper end, creating surrounding recesses called fornices. Anteriorly, it is related to the bladder and urethra.
03 / Function
It is an internal reproductive part, separate from the urethra.
04 / Mechanism
Its flexible muscular walls have a moist lining. Menstrual fluid can pass through it, and it can form the birth passage during vaginal delivery. The urinary tract is separate, even though its opening is nearby.
Working together: reproductive system
Bodies develop in different ways. During puberty, hormones help reproductive organs mature. A pregnancy can begin when a sperm cell fertilizes an egg cell, and development continues in the uterus.

Connect structure with function
The vagina and urethra have separate external openings. Vaginal tissue is adapted to distension, and its appearance and dimensions vary normally.
Check your understanding
Locate the vagina in relation to its neighbors. Explain how the structural features described above support its function, then distinguish it from a nearby structure with a different role.
