FAMILY LIFE

• The Female Reproductive
• Anatomy

2
EGG / OVA

• Female sex cells are produced by the ovaries.
• The largest cell in the human body, about the
  size of a grain of sand.
• One egg is released about every 28 days.
• Each egg has 23 chromosomes.
• Eggs are first released during puberty and are no
  longer released once a woman goes through
  menopause.

• If more than one egg is released, and they are
  both fertilized, the woman would be pregnant with
  fraternal twins.
• Identical twins One egg with a complete split.
• Fraternal twins Two eggs.
• Conjoined twins One egg without a complete
  split.

3
OVARIES

• The ovaries produce eggs, estrogen and
  progesterone from the time of puberty until the
  woman goes through menopause.
• Estrogen and progesterone are the female sex
  hormones.
• Each woman has two ovaries.
• They are approximately the size of an almond.
• The ovaries usually alternate (right and left) in
  releasing eggs from cycle to cycle.

OVARIES
5
FALLOPIAN TUBES

• The inside of the fallopian tubes are
  approximately as thick as a needle.
• There are two fallopian tubes.
• The fallopian tubes have three jobs 1. Catch
  the egg as it is released by the ovaries.
  2. It acts as
  the passageway from the ovaries to the uterus.
  3. Fertilization/Conception
  takes place in the fallopian tubes.

FALLOPIAN TUBES

TUBAL LIGATION

• Female sterilization.
• This operation cuts and plugs the fallopian
  tubes, preventing the egg from reaching the
  uterus and it also prevents the sperm from
  reaching the egg.
• This operation is NOT 100 effective in
  preventing pregnancy and provides NO protection
  against STDs.

TUBAL LIGATION
9
UTERUS

• Also referred to as the womb.
• Where the fetus grows.
• About the size of a womans fist.
• Made out of muscle so that it can stretch as the
  fetus grows and contracts when it is time for the
  baby to be born.
• The lining of the uterus fills with blood so that
  the fertilized egg can receive nourishment and
  get rid of waste products.
• This lining is shed monthly, resulting in the
  womans period.

Umbilical Cord

• The umbilical cord is the connecting cord from
  the developing embryo or fetus to the placenta.
• The umbilical cord supplies the fetus with
  oxygenated, nutrient-rich blood from the
  placenta.

12
PLACENTA AMNIOTIC SAC

• The placenta is a filtering system that develops
  on the wall of a womans uterus. The placenta
  helps to filter out unwanted substances to
  protect the growing fetus and enables the food
  and oxygen to get to the fetus.
• The amniotic sac is a shock absorber that the
  fetus grows in, it is filled with amniotic fluid,
  and protects the baby when the mothers uterus
  accidentally gets hit.

13
PLACENTA AMNIOTIC SACK
14
CERVIX

• It is found at the base of the uterus.
• It is a muscle that stays almost completely shut.
• Only a few sperm at a time can fit through the
  cervixs opening.
• The cervix dilates/opens when the fetus is being
  born, wide enough for the fetus to fit through.

15
CERVIX
16
VAGINA

• Internal
• The BIRTH CANAL.
• It is where intercourse takes place.
• Where sperm is released by the male
• It is a collapsed tube.
• The environment of the vagina is very acidic,
  which helps to prevent infections from occurring.

17
VAGINA
18
LABIA

• Folds of skin that protect the opening of the
  vagina and urethra.
• They are external.
• There are two sets of them the labia
  majora and the labia minora

19
VULVA MON PUBIS

• Vulva Labia Vagina
• Mons Pubis Where the hair grows

20
LABIA
21
HYMEN

• A thin piece of tissue (mucous membrane) that
  partially covers the opening of the vagina.
• This tissue breaks and a small amount of blood
  is released.
• This may break through intercourse, use of a
  tampon, trauma to the area, etc.
• Some women are not born with a hymen, there is no
  known role in the reproductive system for the
  hymen.

22
HYMEN
23
CLITORIS

• It is external.
• It has the most nerve endings and is the most
  sensitive part of the female reproductive
  anatomy.
• Its only purpose is for sexual pleasure and to
  help in the sexual process.

24
CLITORIS
25
BLADDER

• The bladders job is to store urine.
• Both females and males have bladders and their
  jobs are the same for both women and men.

26
BLADDER
27
URETHRA

• Carries urine from the bladder outside the body.
• In the female, only urine travels in the urethra.

28
URETHRA
29
BREASTS

• External.
• The size of the breast is determined by the
  amount of fat tissue present.
• Larger breasts do not produce more milk.
• Mammary glands begin to produce milk once the
  birth has occurred and the mammary glands will
  continue to produce milk as long as the baby
  nurses.
• Breast milk provides the baby with valuable
  vitamins, minerals and antibodies.
