    1. 1. STEPHANIE GARCIA-GOODMAN The FemaleReproductive System
    2. 2. The Uterus The uterus is a hollow, pear-shaped organ also known as the womb.
    3. 3. The Uterus is “home” to the developing fetus.
    4. 4. The Uterus  The fundus is the upper portion whereFundus the fallopian tubes connect to the uterus.
    5. 5. The Uterus  The corpus is the main portion of the uterus which expands to hold the developing fetus.Corpus
    6. 6. The Uterus  The cervix is the lower portion which opens into the vagina. It contains a channel that sperm, and blood can enter and exit through.Cervix
    7. 7. Gestation Gestation is the time required for a fetus to develop. It lasts for 40 weeks, and if a baby is born before 37 weeks, it is considered premature. There are 3 trimesters in a pregnancy. There are 2 stages to gestation.
    8. 8. Gestation: Stage 1 The fertilized egg implants itself into the uterus. The infant is referred to as an embryo. All of the embryos major organs are formed; birth defects may occur. Pregnancy weeks 1-13.
    9. 9. Gestation: Stage 2  The embryo has developed all of its major organs and is now considered a fetus.  The organs mature and begin to function.  The fetus receives nourishment from its mother through the placenta.  Stage 2 is the longest stage of gestation.
    10. 10. The Three Stages of Labor and Delivery
    11. 11. Labor & Delivery Stage 1: Dilation Dilation is the stage when the uterine muscle contracts to expel the fetus. The fetus presses against the cervix and causes dilation and expansion.
    12. 12. Labor & Delivery Stage 2: Expulsion  As the cervix dilates, and becomes thinner it is called effacement.  Once the cervix is fully dilated (10 cm) expulsion begins.  Once the baby’s head appears it is called crowning, but If the baby’s buttocks comes first the baby is breech.  Ends in the birth of a baby.
    13. 13. Labor & delivery Stage 3: Placental This is the final stage of labor. After labor the uterus continues to contract which causes the expulsion of the placenta.
