Female reproductive system definition
The female reproductive system is made up of internal organs external structures. Its function is to enable reproduction of the species. Sexual maturation is the process that this system undergoes in order to carry out its role in the process of pregnancy and birth.
Internal reproductive organs
The uterus, or womb, is a hollow organ located centrally in the pelvis. It houses the developing fetus during pregnancy. The lower portion of the uterus is called the cervix and opens into the vagina, or birth canal. An opening in the cervix allows for the passage of sperm into the uterus and the exit of menstrual blood. This same opening dilates during labor to allow passage of the baby through the birth canal. Arising from the upper portion of the uterus on each side are the Fallopian tubes. These are channels that allow eggs from the ovaries to enter the uterus. The process of fertilization of an egg by a sperm cell typically happens in the Fallopian tubes, and the fertilized egg moves into the uterus where it is implanted. Beside the uterus on each side and near the opening of the Fallopian tubes are the small, oval ovaries. They produce hormones and contain eggs. At birth, a female has 1 to 2 million eggs already present in the ovaries, but only about 300 of them will mature during a woman's lifetime.
