The vagina is the female body part that connects the womb (uterus) and cervix to the outside of the body.
The vagina is a muscular tube lined with mucous membranes. Its opening is between the urethra (where urine leaves the body) and the anus.
Menstrual blood leaves the body through the vagina. The vagina also allows for sexual intercourse, and it is the passageway a baby goes through when it is born.
Inflammation of the vagina is known as vaginitis.
