The Study of the female reproductive system is the medical specialty of Gynecology• The word Gynecology is derived from ancient Greece-gynemeans woman in Greek, ology means the study of.
1. Specifically, Gynecology is practiced to diagnose and treat abnormalconditions of the female reproductive system
Examples of abnormalities of the female reproductive system are:• Cancer• Incontinence of urine• Amenorrhoea-the absence of menstrual periods• Dysmenorrhoea-menstrual periods that cause pain• Infertility• Menorrhagia-heavy menstrual periods• Infections of the vagina, cervix and uterus

2. The three stages of labor and delivery are:• Dilation Stage-The 1st stage. The uterine muscle powerfully contracts to push the fetus out of the uterus and vagina• Expulsion Stage-The 2nd stage. The cervix dilates or expands due to the pressure of the fetus being pushed out in dilation stage. When the cervix is dilated to 10 cm the expulsion of the baby (birth) begins• Placental Stage-The 3rd stage. After childbirth the uterus continues retracting which then causes the placenta to be expelled through the vagina.
Visual representation of the 3 stages of delivery
Terms and conditions of the 3 stages of delivery• Breech presentation-Condition where, during delivery, the babies buttocks will appear first instead of the head.• Labor-The actual process of expelling the fetus from the uterus and through the vagina• Effacement-Condition of when the cervix thins during dilation.• Crowning-When the head, which is usually what appears first, is visible.
3. The tubes that extend from theouter edges of the uterus and assist in transporting the ova and sperm are called uterine tubes a.k.a. fallopian tubes
Fallopian tubes (uterine, oviducts):• Approximately 5.5 inches long• Go from around ovary to either side of the upper portion of the uterus• Have finger-like projections called fimbrae, which catch the ovum leading it into the tube.• The ovum then is ushered into the uterus where it implants itself.• Normally fertilization of the ovum by a sperm occurs in the upper one half of a fallopian tube.
