   The male and female reproductive systems are
    so different that they have to be discussed
    separately, and briefly.
   Both systems are crucial to the continuation of
    the human race, but the female system is
    uniquely equipped to accomplish this task.
   First, the female system produces the
    reproductive cell called ova, and provides a
    place for fertilization and gestation. The breasts
    provide nourishment for the newborn, and the
    female system secretes the female hormone.
   There are two ovaries, one on each side of the
    uterus, within the pelvic cavity. Theses almond
    shaped glands produce ova and the female sex
    hormone. Approximately every 28 days,
    stimulated by follicle stimulating hormone
    (FSH), and luteinizing hormone (LH),
    ovulation occurs. One ovary releases one
    ovum. Estrogen and Progesterone prepare the
    lining of the uterus to receive a fertilized ovum.
    These hormones are responsible for the
    secondary female sexual characteristics.
   The fallopian tubes, also called uterine and
    oviducts, extend like fingers at the end of the
    fallopian tubes, (fimbriae), and catch an ovum
    after ovulation, propelling it to the uterus
    where it can implant.
   If the egg meets with sperm fertilization will
    occur in the upper half of the fallopian tubes.
   In a normal pregnancy the fertilized ovum
    implants in the endometrium, an inner layer of
    the uterine wall that is rich in blood supply and
    nourishments for a developing baby.
   If a pregnancy is not established, the endometrium is
    sloughed off and menstruation results. A girls first
    menstrual period is called menarche and the end of
    menstrual activity is called menopause.
   Pregnancy is the period of time when the baby grows
    and develops in its mothers uterus. Pregnancy,
    (gestation), is 40 weeks. If a baby is born before 37
    weeks it is considered premature.
   From the time of fertilization until the end of eight
    weeks the infant is referred to as an embryo. This is the
    time when all of the major organs are formed. After
    this period until birth the infant is called a fetus.
    During this longest stage of gestation the organs
    mature and begin to function. The fetus receives
    nourishment from the mother through the placenta.
   The process of expelling the fetus from the
    uterus through the vagina is called labor.
    During the first stage,(dilation), the uterine
    muscles contract strongly to expel the fetus.
    The fetus presses on the cervix causing it to
    dilate/expand. Once the cervix is dilated 10
    centimeters the expulsion stage begins. The end
    is delivery of the baby. Usually the crown or
    head appears first but in some cases the
    buttock appear first resulting in a breech
    presentation. Immediately after birth the
    placenta is expelled through the vagina.
