REPRODUCTIVE SYSTEMS By the end of this unit, you will be
able to:discuss and describe the organs of the
male and female reproductive system; identify the different parts of the male
and female reproductive system on a diagram;
discuss certain male and female health concerns related to the reproductive system.
FEMALE REPRODUCTIVE SYSTEM
The female reproductive system’s primary function is for reproduction.
An egg cell (ovum) is produced which, when united with a sperm cell, will eventually form a baby.
FEMALE REPRODUCTIVE SYSTEM
Although the female has external and internal reproductive organs, the organs of the system are primarily internal.
The external organs are called the vulva.
FEMALE REPRODUCTIVE SYSTEM
The vulva consists of the:ClitorisMons pubisLabia majora (Outer lips)Labia minora (Inner lips)Vaginal opening
FEMALE REPRODUCTIVE SYSTEM The clitoris is a knob of tissue, located in
front of the vaginal opening.
The clitoris has no reproductive function, but is important in producing sexual arousal.
The mons pubis is a rounded, fatty pad of tissue, covered with pubic hair.
The mons pubis is located on top of the pubic bone.
FEMALE REPRODUCTIVE SYSTEM
The labia majora (outer lips) is the outer fold of tissue on either side of the vaginal opening.
The labia minora (inner lips) is the inner folds of skin which are inside the labia majora. The labia minora form a hood over the clitoris.
FEMALE REPRODUCTIVE SYSTEM
The functions of the labia are:To protect against germs entering the bodyFor sexual arousal
The vaginal opening is visible with the labia are parted.
Vaginal Opening
FEMALE REPRODUCTIVE SYSTEM
The internal organs are the:VaginaUterusFallopian tubesOvaries
FEMALE REPRODUCTIVE SYSTEM The vagina is a tubelike passageway,
about 4 to 5 inches long.
It is also called the birth canal; it stretches to allow for the birth of a baby.
The vagina leads to the cervix (the neck of the uterus).
The cervical opening is very small, but during child birth it opens (dilate) for the baby.
FEMALE REPRODUCTIVE SYSTEM The hymen is a thin membrane, located
just inside the vaginal opening.
The hymen has no particular function and is not present in all females.
There are many myths related to the hymen, but many are not true.
Some women may feel discomfort with the breaking of their hymen.
FEMALE REPRODUCTIVE SYSTEM
The uterus is a strong, elastic muscle, about the size of a fist.
The primary function of the uterus is to hold and nourish a fetus (developing baby).
FEMALE REPRODUCTIVE SYSTEM
On each side of the uterus are the Fallopian tubes.
Fertilization of the ovum (the joining of a sperm cell and egg cell) occurs in the Fallopian tubes.
FEMALE REPRODUCTIVE SYSTEM
The ovaries are the female sex glands on both sides of the uterus.
The function of the ovaries are:Production of female sex hormones
(estrogen and progesterone)House the egg cell (ovum)
FEMALE REPRODUCTIVE SYSTEM Ovulation is the process of an ovary
releasing a mature egg cell (ovum) into that ovary’s Fallopian tube.
A ovum can live for about two days in the Fallopian tube.
If sperm are present, one sperm will enter the ovum. This is call fertilization. Pregnancy begins at this point.
FEMALE REPRODUCTIVE SYSTEM
If the ovum is fertilized, it moves into the uterus and attaches to the lining.
The ovum will develop into a baby while in the uterus.
FEMALE REPRODUCTIVE SYSTEM If the ovum is not fertilized, it dies and
passes into the uterus.
The uterine lining is not needed because there is no pregnancy, so the uterine muscles begin to contract and the lining of the uterus is shed.
This lining passes through the vagina and out of the body during a process called mestruation.
FEMALE REPRODUCTIVE SYSTEM Menstruation (also called a period)
usually takes 4 to 7 days, but can be shorter or longer. Each female’s menstrual period is different.
During menstruation, the female loses between 2 and 3 tablespoons of blood in additional to the uterine lining (tissue).
FEMALE REPRODUCTIVE SYSTEM Almost all females being menstruating
between the ages of 10 and 15.
Hormones control the menstrual cycle so each female’s cycle is unique to her.
FEMALE REPRODUCTIVE SYSTEM
Menstruation Cycle
FEMALE REPRODUCTIVE SYSTEM Because the uterus contracts to break
down the lining, the female may experience cramps.
Light exercise, a warm bath, or a heating pad will relax the muscles to assist with the cramps.
Severe cramps require medical attention.
FEMALE REPRODUCTIVE SYSTEM Bathing of the vaginal area is important,
but becomes even more important during menstruation.
Sanitary napkins or tampons must be used to catch the menstrual flow, and must be changed every 3 to 4 hours.
Tampons left in for more than 4 hours increases the risk of infection.
FEMALE REPRODUCTIVE SYSTEM
Women have certain reproductive health issues:
Premenstrual Syndrome (PMS)
Sterility
Breast Cancer
FEMALE REPRODUCTIVE SYSTEM Premenstrual Syndrome (PMS) refers
to a variety of symptoms females experience during menstruation, including:Nervous tensionAnxiety IrritabilityBloatingWeight gainDepressionMood swingsFatigue
FEMALE REPRODUCTIVE SYSTEM The causes of PMS are not fully
understood, but may be related to hormones or nutritional deficiency.
Most doctors recommend diet and life-style changes.
PMS sufferers must try to reduce stress, and reduce their intake of sugar, salt, caffeine, nicotine, and alcohol.
FEMALE REPRODUCTIVE SYSTEM
Women can become sterile through:
A blockage in one of both of the Fallopian tubes
The inability to ovulate
Endometriosis, a condition in which uterine tissue grows outside the uterus, in the pelvic cavity.
FEMALE REPRODUCTIVE SYSTEM Breast cancer is the second leading
cause of death of women after lung cancer (US).
Breast cancer is not preventable, but it is treatable and curable.
Females with a family history of breast cancer are twice as likely to develop this cancer.
FEMALE REPRODUCTIVE SYSTEM Women should complete monthly self-
breast examinations.
Symptoms of breast cancer (in women and men) are:Change in breast or nipple appearanceLump or swelling in the breastLump under the armpit
