An essential function of all living things is reproduction.
Reproduction- the process by which life continues from one
generation to the next.
Slide 3
In humans, as in many other species, reproduction results from
the union of two sex cells, one from the male and one from the
female.
Slide 4
The Reproductive System- The system of organs involved in
producing offspring
Slide 5
The female reproductive system has several functions: 1. It
produces female sex hormones and stores female reproductive cells
(ova). 2. The uterus nourishes and protects the fertilized ovum
from conception until birth.
Ovaries Female sex glands that store the ova and produce female
sex hormones.
Slide 10
At birth a females ovaries contain more than 400,000 immature
eggs (ova). Beginning at puberty, one ovum matures each month
Slide 11
Ovulation The process of releasing a mature ovum into the
fallopian tube each month. The right ovary will release a mature
ovum one month, and the left ovary will release one the next
month.
Slide 12
Fallopian Tubes A pair of tubes with fingerlike projections
that draw in the ovum.
Slide 13
Fallopian tubes continued Tiny hair like structures called
cilia work along with the muscular contractions to move the ovum
along inside the fallopian tubes.
Slide 14
Slide 15
Endometrium The lining of the uterus (the womb). It grows and
sheds each month during the menstrual cycle. The endometrium then
grows back and slowly gets thicker and thicker until the next
period when it is once again shed.
Slide 16
Slide 17
Uterus A hollow muscular pear-shaped organ inside a females
body. It nourishes and protects the fertilized ovum from conception
until birth.
Slide 18
Slide 19
Cervix The lower part of the uterus that connects the uterus to
the vagina. The cervical canal passes through the cervix, allowing
the menstrual period and fetus to pass from the uterus into the
vagina, and sperm to pass from the vagina into the uterus
Slide 20
Slide 21
Vagina A muscular elastic passageway that extends from the
uterus to the outside of the body. This is where menstrual blood,
vaginal fluids and babies leave the body.
Slide 22
Slide 23
Menstruation- Shedding of the uterus lining.
Slide 24
Menstruation continued : A period is when a woman's body
releases tissue it no longer needs. This tissue comes from the
uterus, which is where a baby (fetus) develops in the female body.
Every month or so, the uterus lining gets thicker. This is to
prepare for a fertilized egg if the woman becomes pregnant.
Slide 25
Menstruation continued: If the egg doesn't get fertilized, that
lining is released from the body through the vagina. This is called
menstruation. So when a girl has her period she is not "bleeding"--
her body is just getting rid of a small amount of blood and some
un-needed tissue. It is a natural, normal body process.
Slide 26
The Menstrual Cycle (Menstruation is part of the menstrual
cycle) A cycle is counted from the first day of one period to the
first day of the next period. The average menstrual cycle is 28
days long
Slide 27
Menstrual Cycle continued: In the first half of the cycle,
levels of estrogen (the female hormone) start to rise and make the
lining of the uterus (womb) grow and thicken. At the same time, an
egg (ovum) in one of the ovaries starts to mature. At about day 14
of a typical 28-day cycle, the egg leaves the ovary. This is called
ovulation The Period
Slide 28
Problems related to menstruation: Menstrual cramps -
(constriction and tightening of the uterine muscle) occur at the
beginning of the period. Premenstrual syndrome (PMS) caused by
hormonal changes. May be experienced 1 2 weeks before. Symptoms
include: irritability, bloating, weight gain, mood swings, and
fatigue.
Slide 29
Problems related to menstruation continued: Toxic Shock
Syndrome (TSS) rare but serious bacterial infection that affects
the immune system and the liver and can be fatal. To reduce risk,
CHANGE TAMPONS OFTEN! Symptoms include: fever, vomiting, diarrhea
and dizziness.
Slide 30
Menopause A time in a womens life when her period stops. It is
a normal change in a woman's body. A woman has reached menopause
when she has not had a period for 12 months in a row (and there are
no other causes, such as pregnancy or illness, for this change).
Normally happens between the ages of 45- 55
Slide 31
Care of the Female Reproductive System Bathe Regularly During
menstruation, pads and tampons must be changed every few hours.
Practice Abstinence Abstain from sexual activity to avoid unplanned
pregnancy and STDs.
