The vagina, vulva and clitoris

The vagina is the passage that leads from the cervix to the vulva.
The cervix is at the bottom of the womb (uterus).
The vulva is visible from outside the body.
It forms the skin flaps around the entrance to the vagina.
The outer flaps are called the labia majora and the inner flaps are called the labia minora.
The clitoris sits at the top of the labia minora and is very sensitive to touch.
This gives women a lot of their sexual pleasure.
During sexual arousal there is an increased blood flow to this area, which leads to
swelling and extra sensitivity in the vulva and clitoris.
