The female reproductive system includes the ovaries, fallopian tubes, uterus, vagina, and vulva. The ovaries produce eggs and hormones, the fallopian tubes transport eggs to the uterus, and the uterus provides support for embryo development and pregnancy. If pregnancy does not occur, the uterine lining sheds through menstruation. During pregnancy, the embryo implants in the uterine lining and develops into a fetus, with the placenta providing nutrients. Childbirth involves contractions and cervical dilation that push the fetus through the birth canal.
