A woman's vagina, also called the birth canal, is part of the
reproductive tract and extends from the uterus to outside the body. The
opening to the vagina is located between the bowel opening (anus) and the
opening for the bladder (urethra).
Blood from a woman's menstrual period flows through her vagina.
During sexual intercourse, sperm are ejaculated from the man's penis into the
vagina and travel through the cervical canal and uterus to the fallopian tubes,
where fertilization can occur.
