Title: In this lesson, you will learn to
1The Female Reproductive System
Unlike other body systems, the reproductive
system is different for males and females
- In this lesson, you will learn to
- identify the parts of the female reproductive
system. - describe the functioning of the female
reproductive system. - identify problems of the female reproductive
system. - recognize the importance of early detection in
the treatment of conditions of the female
reproductive system. - describe ways to keep your reproductive system
healthy.
2Reproductive System
- The body system containing the organs that make
possible the production of offspring
3The Female Reproductive System
Three Functions of the Female Reproductive System
Create offspring
Store egg cells
Give birth
to allow fertilization to occur
to nourish and protect the fertilized egg
4Female Reproductive Organs
- ovaries
- fallopian tubes
- fimbriae
- uterus (womb)
- cervix
- vagina
- mons pubis
- labia majora (outer lips)
- labia minora (inner lips)
- vaginal opening
- hymen thin membrane partially covering the
opening of vagina - clitoris
Vulva the external part of the female
reproductive organs . external genitalia
5- ovaries
- female sex glands
- two rounded organs, one on either side of the
uterus - contains the ova, eggs, and hormones that cause
the egg to mature - estrogen
- progesterone
- ova (ovum)
- egg, female sex cells
- a female is born with hundreds of thousands of
immature ova in her ovaries - from puberty to menopause hormones cause ova
mature - a few hundred will mature during reproductive
years
- Female Reproductive Organs
6- fallopian tubes
- tubes that carry eggs, ova, from ovaries to
uterus - fimbriae
- finger-like projections at the end of the
fallopian tubes that reach out and grab the
egg as it leaves the ovary
- Female Reproductive Organs
7- uterus (womb)
- pear shaped hollow muscular
- organ that receives, holds, and
- nourishes the fertilized ovum during
- pregnancy
- with thick muscular walls
- which are
- the thick muscular walls
- are highly elastic and can stretch many
times its normal size -
-
-
Female Reproductive Organs
- Endometrium
- the uterine lining bloody tissue lining
- thickens to prepare for the attachment
- of the embryo
- is shed during monthly menstrual period
- if pregnancy does not occur
-
8Female Reproductive Organs
- cervix
- the neck of the uterus, (lower portion)
- protrudes into the top of the vagina
- the passageway between the uterus and the vagina
- site of glands that secret mucus to lubricate the
vagina -
9- vagina
- an elastic, muscular tube that is a passage way
between the uterus and the outside of the body,
(vulva) - also called the birth canal
- the female organ for intercourse
- repository for semen when a male ejaculates with
the penis inside the vagina during intercourse - It is possible for the sperm to enter the
reproductive system if the male ejaculates near
the vagina - 3 to 4 inches long
- capable to stretch for birth of baby
Female Reproductive Organs
- Vulva
- the external part of the female reproductive
organs . - external genitalia
10- ovulation when a mature ovum,(egg) is released
from the ovaries - it travels along the fallopian tubes to the
uterus - usually once a month from one ovary
- an ovum can live about a day in a fallopian
tube - ova (ovum)
- egg, female sex cells
- a female is born with hundreds of thousands of
immature ova in her ovaries - from puberty to menopause hormones cause ova
mature - a few hundred will mature during reproductive
years - IF A SPREM IS PRESENT AND ONE SUCCESSFULLY
PENETRATES THE OVUM - Fertilization
- union of a sperm and an egg to form a single
cell PREGNANCY

12MenstruationThe menstrual period
- the process of shedding the uterine lining
(discharging blood and tissue out of the female
body) - Occurs only when an ovum is not fertilized
- Page 38 in Human Sexuality Book
13menstrual cycle
- the time from one menstruation to another
- first day of period to first day of next period
- usually 28 days
- starts at puberty and continues until menopause
- due to increase levels of hormones
- purpose is to prepare the body for fertilization
get ready to have a baby
144 stages of the cycle
- Days 1-8 menstruation menstrual period
- about 5-7 days average not always
- Days 9-13 days before release egg
- hormones cause an egg to mature in one ovary
- body is preparing for egg
- Day 14 ovulation egg is released into one
fallopian tube - 14 days before menstrual period
- 4. Days 15-28 days after egg is released egg
travel through the fallopian tube to the uterus
waiting to be fertilized - IF EGG NOT FERTILIZED CYCLE BEGINS AGAIN

16THINGS YOU SHOULD KNOW
- the average length of the menstrual cycle is 28
days, however - it is normal for the cycle to be longer or
shorter - Blood passing out of the body is about 3-10 table
spoons - This is blood the body does not need so it does
not make the women ill or weak - the most likely time to get pregnant is around
ovulation time - ovulation occurs on or about 14 days before your
period starts regardless of the length of your
cycle - to count the days of the menstrual cycle
- day 1 first day of menstrual period
- last day of cycle day before your period
starts again - Menstruation continues until menopause
17Menstrual Problems
A variety of menstrual problems can affect girls.
Some of the more common conditions are
- Cramps uterus is contracting
- mood swings or sadness hormones
- Less often
- painful periods
- very heavy periods with excess bleeding.
- missed or infrequent periods, even though she's
been menstruating for a while and isn't pregnant.
18Problems of the Female Reproductive System
Infertility This is the inability to get
pregnant. It may be due to blocked fallopian
tubes, a failure to produce eggs, endometriosis,
or and STD left untreated. Ovarian cysts These
are growths on the ovary. Symptoms of ovarian
cysts include a feeling of heaviness in the
abdomen and abdominal pain, swelling, and
bloating. Infections - Vaginitis inflammation
of vaginal tissue, Yeast infections symptoms
inflammation of vaginal tissue, discharge,
burning, itching,
and painful urination Toxic shock syndrome -
Associated with tampon use and some contraceptive
devises symptoms include fever, chills,
vomiting, diarrhea, rash Cancer Breast
Cervical Sexually Transmitted Diseases
(STDs) These are diseases spread through sexual
contact.
19GynecologistGYN
- a physician who specializes in caring for the
female reproductive system - women should start to see a gynecologist by
about age 18 or when they begin to be sexually
active
20Caring for The Female Reproductive System
- Practice abstinence from sex - this can prevent
infections with HIV and other STDs - Bathe or shower daily - keep the external
reproductive organs clean especially during
menstruation. - Sanitary pads and tampons should be changed often
- every four hours. - Perform self breast examinations - a way to check
your own breast for lumps or tenderness. - Have regular medical checkups Pap Test - a
physician can answer any question she has.
Gynecologist. - Get medical attention for signs of infection -
lumps, sores, rashes, or a discharge that require
medical attention.
21- What happens if an egg is not fertilized?
- It is eliminated from the body through
menstruation ... Woman has her period - What happens if it is fertilized?
- An egg that is fertilized moves down into
uterus and implants in the endometrium and
develops into a baby.. No period
22- What are the three most important functions of
the female reproductive system? - to store eggs
- to allow fertilization to occur
- to nourish and protect the fertilized egg until
it is ready to live outside the females body
