The female reproductive system consists of internal and external organs that work together to produce eggs, facilitate fertilization and pregnancy, and nourish infants. The internal organs include the uterus, ovaries, fallopian tubes, and vagina. The ovaries produce eggs and hormones, the fallopian tubes transport eggs to the uterus, and the uterus houses and nourishes an embryo. The external genitalia include the vagina and breasts. The vagina receives sperm and acts as the birth canal, while the breasts produce milk to nourish newborns.
