Chapter 8 Female Reproductive System

2 Female Reproductive System
Sexual reproduction is the union of the nuclei of the female sex cell (ovum) and the male sex cell (sperm) that results in the creation of a new individual Sex cell is called a gamete Gametes are produced in special organs call gonads. (female=ovaries; male= testes) An ovum leaves the ovary and travles down the fallopian tubes. If coitus (sexual intercourse) occurs and sperm cells are present in the fallopian tubes, fertilization may take place. The embryo then will begin a 40 wk gestation/ pregnancy in the uterus

3 Ovaries Ovary= (oophor/o or ovari/o) Ovary=Female gonads or sex glands
Located in the pelvic cavity and attached to the uterus by ligaments Graafian Follicles: small sacs in the ovaries containing immature ovum. When the ovum matures, the follicle releases the ovum and ovulation occurs Bilateral Oophorectomy: (oophor/o=ovary; -ectomy= removal); female castration; removal of both ovaries Bilateral Salping-oophorectomy: (salping/o=fallopian tubes; removal of both the fallopian tubes and ovaries Pelvic exenteration- removal of internal and external organs in the region of the hip

4 Fallopian Tubes Adnexa Uteri- (adnexa=accessory); fallopian tubes and ovaries are considered accessory organs Fallopian Tubes; (salping/o) Two tubes attached to the upper part of the uterus Lateral ends located above the ovaries but no direct connection Fimbriae: finger-like projections help move the ovum from the ovary to the fallopian tube Passageway for ovum as it moves from the ovary to the uterus Fertilization typically takes place in the fallopian tubes Ectopic pregnancy: (ec-=outside; top=place/position; -ic= pertaining to); pregnancy outside the uterus often occurring in the fallopian tubes Pyosalpinx- Py/o= pus; pus (infection) in fallopian tubes

6 Uterus Uterus: (metr/o; metr/i; uter/o)
Hollow, muscular , pear-shaped organ Located behind urinary bladder but in front of the rectum in pelvic cavity Three parts: Fundus- top section Corpus- body of organ Cervix- (neck) bottom section that attaches to the vagina Pap Smear- test for cervical cancer

7 Uterus Functions: Organ of menstruation
Allows for the development and growth of the fetus Contracts to aid in expulsion of fetus during birth Three Layers: -Endometrium- (endo=in, within; metri/i=uterus) epithelial mucosa of uterus; layer that sloughs off during menstruation -Myometrium- (my/o=muscle; metr/i=uterus) the middle, muscular layer -Uterine Serosa: outer, membranous tissue layer

8 Female Reproductive parts
Vagina- (colp/o); muscular tube that connects cervix of uterus to the exterior of the body (PH acidic) Coloposcopy- visual exam of the vagina Vulva- (vulv/o); external female genitalia - Bartholin’s glands= two small glands on either side of vaginal opening that secretes mucous for lubrication Labia Majora= outer lips of vagina Labia Minora= smaller, inner lips of vagina Clitoris= sensitive, erectile tissue Perineum= region b/w vaginal orifice and anus Episiotomy- (episi/o=vulva; -tomy= incision) incision of perineum during childbirth

9 Breasts or Mammary Glands
Located in the upper anterior region of chest Contain lobes separated into sections of connective and fatty tissues Milk ducts (lactiferous) located in tissue on surface of nipple Aerola- dark pigment around the nipple Mammary papilla- nipple of the breast Gynecomastia- (gyn/o=women); abnormal development of breast tissue in a MALE

13 Menstruation Menarche= the beginning of menstruation at the time of puberty Menstruation- monthly discharge of blood from the lining of the uterus Metrorrhagia- excessive flow b/w periods FSH- _______________________________ Produced by the endocrine gland located below the brain LH-_________________________________

14 Menstruation and Pregnancy
Menstrual cycle is divided into 28 days and 4 intervals Day 1-5= shedding of uterine lining and bleeding is discharged through vagina (menstruation); FSH causes follicles to enlarge and secrete estrogen (begins endometrial repair) and sm amounts of progesterone Day 6-12= endometrium begins to repair itself as the hormone estrogen is released by the graafian follicle in the ovary; surge of LH and the follicle ruptures and expels ovum leading to ovulation Day 13-14= ovulatory period (graafian follicle ruptures and the egg leaves the ovary to travel down the fallopian tube Day 15-28= Estrogen and progesterone (hormone needed to sustain pregnancy and stimulates FSH & LH to shut off) are released and stimulates the building up of the endometrium in anticipation of fertilization; without fertilization FSH &LH shut down, estrogen and progesterone drop and endometrium begins process of sloughing off again ***Days 12-15= Most likely to become pregnant during coitus

16 Pregnancy If fertilization occurs, the fertilized egg (zygote) travels to the uterus Implantation occurs in endometrium Placenta= vascular organ now forms within the uterine wall Fetus is surrounded by amnion and amniotic fluid Placenta produces a hormone called HCG (Human Chorionic Gonadotropin); this is the hormone tested for in pregnancy tests Pregnancy lasts for 9 months (gestation) Fetus is delivered with uterine contractions and this stimulates the cervix to dilate (widen) Placenta is delivered and known as “afterbirth”

17 Terms Neonatology- (neo=new; nat/i=birth;
-logy=study of); study of and treatment of newborns Parturition= the act of giving birth Dystocia= painful labor and deliver Oxytocia= rapid labor Cephalic Version- turning the fetus during delivery Hysterectomy: (hyster/o=uterus, womb); Surgical removal of uterus -parous= to bring forth or bear -gravid/o= pregnancy

18 Contraception Birth Control Pills: works on negative feedback mechanism; decreases FHS and LH from the anterior pituitary gland and thus no ovulation occurs=no fertilization Diaphragm: A diaphragm is a thin rubber dome with a springy and flexible rim. It is inserted into the vagina, fits over the cervix and is held in place by vaginal muscles. A diaphragm holds spermicide in place over the cervix (opening to the uterus). Spermicide kills sperm, preventing fertilization. After intercourse, it should be left in place for 6-8 hours. Diaphragms are 86-94% effective as birth control.

19 Intra-Uterine Device (IUD)
IUD: Intra-Uterine Device; plastic or copper wire placed in uterus for long period of time; can cause PID

20 Contraception Norplant- sub-dermal implants containing estrogen and progesterone can be effective up to 5 years Condom- latex covering over the tip of the penis and traps the sperm - Tubal Ligation- surgical sterilization to present the passage of the ovum -Rhythm Method- temporary abstinence; avoiding intercourse during 4 days before ovulation and 3 days after ovulation

21 Contraception Mini-Pill - Unlike the pill, the mini-pill only has one hormone, progestin, instead of both estrogen and progestin. Taken daily, the mini-pill thickens cervical mucus to prevent sperm from reaching the egg. It also prevents a fertilized egg from implanting in the uterus (womb). The mini-pill also can decrease the flow of your period and protect against PID and ovarian and endometrial cancer. A back-up method of birth control is needed if you take the pill more than three hours late.

22 Contraception The Female Condom – Worn by the woman, this barrier method keeps sperm from getting into her body. It is made of polyurethane, is packaged with a lubricant, and may protect against STDs, including HIV. It can be inserted up to 24 hours prior to sexual intercourse. Female condoms are 79 to 95% effective at preventing pregnancy. There is only one kind of female condom, called Reality.

23 Contraception Depo-Provera – With this method women get injections, or shots, of the hormone progestin in the buttocks or arm every 3 months. It does not protect against STDs or HIV. Women should not use Depo-Provera for more than 2 years in a row because it can cause a temporary loss of bone density that increases the longer this method is used. The bone does start to grow after this method is stopped, but it may increase the risk of fracture and osteoporosis if used for a long time. It is 97% effective at preventing pregnancy. The Patch (Ortho Evra) –This is a skin patch worn on the lower abdomen, buttocks, or upper body. It releases the hormones progestin and estrogen into the bloodstream. You put on a new patch once a week for three weeks, and then do not wear a patch during the fourth week in order to have a menstrual period. The patch is 98 to 99% effective at preventing pregnancy, but appears to be less effective in women who weigh more than 198 pounds. It does not protect against STDs or HIV.

24 Contraception Contraceptive Sponge - This is a barrier method of birth control that was re-approved by the Food and Drug Administration in It is a soft, disk shaped device, with a loop for removal. It is made out of polyurethane foam and contains the spermicide nonoxynol-9. Before intercourse, you wet the sponge and place it, loop side down, up inside your vagina to cover the cervix. The sponge is 84 to 91% effective at preventing pregnancy in women who have not had a child and 68 to 80% for women who have had a child. The Hormonal Vaginal Contraceptive Ring (NuvaRing) – The NuvaRing is a ring that releases the hormones progestin and estrogen. You squeeze the ring between your thumb and index finger and insert it into your vagina. You wear the ring for three weeks, take it out for the week that you have your period, and then put in a new ring. The ring is 98 to 99% effective at preventing pregnancy. Pulmonary embolism (PE), deep vein thrombosis (DVT), and ischemic strokes are some of the side effects being associated with NuvaRing.
