This is John Burke class of nineteen forty.
This is Mary Burke class is nineteen forty.
This is John Burke Jr class of nineteen sixty six according to the fond hopes of
his parents.
Someday you may be in John Burke shoes
or in Mary Burke High Heels slippers.
What are you going to do or say
when something like this takes place in your own household.
Mary I forgot to tell you Jim was at the office today.
He took Helen to the Spittal
that I guess are pretty excited. You think I should telephone the phone.
Well Jim will call as soon as the baby is born.
I don't know which of them will be satisfied.
I know Helen has a heart set on a girl
and I know Jim has his heart set on a boy I am going to telephone the hospital.
If they don't know like the boys mete Johnny they'll love their little baby whether
it's a boy or a girl.
Yes my mother's bring them into the world where I
do Johnny by the grace of Heaven mothers are the only ones who know how to bring
babies into the. That's right. Dads mothers do bring babies into the world.
But sooner than you might think.
Now your child will be old enough for a full explanation. So let's brush up on it.
You and I and together reveal the human reproductive system.
A model will help you reveal the fundamentals.
That the male sex organs as seen from outside consist of several folds of skin
or tissue called a lady a toilet.
These Lady A cover the array spread through which urine is that.
And the entrance to the vagina.
Cutting through this model these organs can be seen as they actually appear in
vertical section through the midline here is the vagina the vagina has the most
lining called the mucous membranes its walls lie in folds which can be easily
stretched a membrane partly covers the entrance to the vagina.
This is the hymen or Maidenhead.
Its absence does not mean lack of rigidity
and it may be accidentally broken during childhood. And the uterus.
Shown here on the front of you is a small pear shaped organ normally only about
half the size of those that they low it is a vagina.
And connected to it at the top are two to the fallopian tubes.
And the two ovaries.
In a section through these organs.
We can see the cervix this is the narrow neck of the uterus
and it extends into the vagina. The walls of the uterus are very thick.
But may be stretched so
that the uterus can enlarge too many times its original size. During pregnancy.
One end of the fallopian tube is open so
that eggs for over from the adjacent overate may easily answer
and be carried to the uterus.
The ovary is a gland in which eggs are constantly being formed.
Each am in the shape over a is about an inch and a half in length.
The Zeid producing eggs.
These glands secrete fluids into the blood which are responsible for the
development of the male characteristics in other parts of the body such as breasts
pear and skin
but from puberty on the primary function of the older A's is the production of eggs
in a closer view we can watch the development of an egg.
Remember that while this one is growing all the others are growing also
but usually only one egg reaches maturity
and rate twenty eight days after
reaching full development. It breaks through the ovarian wall
and passes into the fallopian to this breaking through of the egg is called
relation.
The fully developed egg is only one two hundredth of an inch in diameter.
When mature each egg is capable if fertilized of developing into a baby.
Moreover each egg carries all of the hereditary characteristics of the mother.
Since the function of the uterus is primarily
that of receiving the fertilized egg
and nourishing the developing child the walls undergo regulars.
By the look preparation for this job.
The lining of the uterus becomes soft and spongy and engorge with blood
and fluids this progresses during the final stages of the development of the egg
extrusion from the older A
and its passage through the two if fertilization of the egg does not occur.
The uterine wall lining breaks down
and is this jarred from the body as the menstrual flaw.
If we call this onset of menstruation the first day of the menstrual cycle we can
watch the various elements as a record during each twenty eight day period after
the menstrual flow stops about the fourth day.
The uterine lining begins to build up again.
Meanwhile eggs are being formed in the ovaries in the normal cycle all the elation
occurs about the fourteenth day and an egg is extruded into the fallopian tube.
It started slow passage toward the uterus.
But it's not fertilized it dissolves away or disappears in the two.
After the twenty eight day menstruation occurs again
and the cycle is repeated.
This lamb is the structure
and function of the female reproductive organs the ovaries which every twenty eight
days discharge mature eggs into the FULL OF THE into the uterus
which during the same period gets ready to receive the egg in case it is fertilized
by contact with the male sperm if fertilization of the eggs does not occur
or the egg itself dissolves or disappears
and the uterine wall linings now deprived of their special function to nourish the
developing child break down and.
Are discharged as a menstrual flaw.
Although the average menstrual cycle usually occurs every twenty eight days in many
cases it may be somewhat longer
or shorter because it depends on the proper functioning of many glands its normal
time schedule may be easily upset by nervous strain emotion
or illness the process is regularly repeated however every twenty eight days on
less fertilization of the egg occurs and pregnancy begins.
These are the facts of the female reproductive system.
This is the information which you dad should clearly understand before you can pass
on correct knowledge to your child when he is old enough to understand why yes.
Why do you all there wouldn't be any babies without fathers.
Well your child isn't good as it is one day you'll have to tell him why babies do
have fathers and
that brings us to the next chapter in our review of the story of reproduction the
structure and function of the male reproductive organs the X.
Journal male reproductive organs as shown in this drawing consists of the penis
and this growth on this growth and contains the testicles.
In a section view we can see that the penis
and testicles are connected by a LONG TO THIS is the arrays broken now.
It extends from the penis back past the prostate gland
and seminal vesicles to join the two bleeding from the testicles.
In this same diagram we can see also the bladder which empties into the original
canal the testicles in men correspond to the ovaries in women
because they. Those are gland in which the reproductive elements are formed.
If we examine a section of the testicles.
We find that it is composed of small compartments filled with two kinds of cells.
One kind produces an internal secretion which is carried in the blood
and results in the development of male characteristics such as skin beard voice
and body structure.
The second
or lining cells are constantly being changed into spermatozoa spermatozoa are the
male sex sells these parameters Allah
or sperm cells are microscopic single cells which are propelled by the lashing
motion of their long tails like the all the more egg of the female.
Each sperm cell contains all the hereditary characteristics which are passed from
the father to the child spermatozoa are constantly being formed in the testicles
and are stored in the massive curled Tube seen here.
If not empty during sexual intercourse.
They are periodically empty during sleep in nocturnal emissions are wet dreams.
Where premiums are a perfectly normal body function which is nature's way of
getting rid of stored up sperm.
Therefore the common belief that intercourse
or masturbation are necessary to relieve the pressure of stored up sperm is
absolutely not true.
Millions of spermatozoa are stored ready for ejaculate during intercourse
the penis is in a state of erection.
This is caused by the spongy tissues of the penis becoming in gorge with blood
that sperm passes up through the duct. Where fluids from the glass.
And they're added to form the theme and the theme
and then flows through the array throw can now
and is deposited into the female giant.
We return now to the female organs with the eggs lowly moving through the tube male
sperm are deposited at the upper end of the vagina near the cervix.
They begin moving up into the uterus.
Sperm may remain active here for several days.
The sperm move into the tube and approach the egg in this diagram both the egg
and the spermatozoa are greatly enlarged in proportion to the size of the organs
shown.
Normally fertilization takes place while the egg is in the two.
Here we can see this bird was Asian in closer view.
After one sperm a result one enters the egg no other is entered
the tail drops off the nuclei of sperm and egg merge
and the development begins.
The fertilized egg develops by first splitting into two.
Then into four eight
and so on from this fusion of a single egg
and as thing those parameters on the child develops these early divisions take
place while the fertilized egg is still moving through the tube as you may recall
the uterine wall has during this part of the menstrual cycle then preparing to
receive this day the wall is rich with blood
and limbs from which the growing organism will draw its nourishment its nesting of
the egg against that you are in the wall brings about many glandular actions.
These first causes.
Station of menstruation
and then during the course of the exit of element into a baby produce the many
secondary physical
and physiological characteristics of pregnancy after the first two weeks this
fertilized egg enters the embryos De Gea the embryo itself lies along the inner
margin of the yolk sac
and is in turn connected by a stock to the membrane through which food will be
absorbed at this time the embryo is still almost microscopic in size
but the largest portion is the yolk sac which provides early nourishment the
development of the embryo is an interesting
and highly complex process during the first four weeks the embryo increases rapidly
inside the yolk sac becomes progressively smaller as it is absorbed.
But the mechanism for feeding from the mother has in the meantime been developed.
At the fourth week buds have appeared where the limbs will develop
and the embryo has now taken definite form during the next
months the limbs assume more specific shape
and the head becomes large as the brain develops the foetus as it is now called
resembles most other mammals
that a similar stage of growth during the third
and fourth months the fetus develops all the human facial characteristics.
The thing years and tollers and the external sex organs.
At the end of the fourth month the foetus average is about six inches in length
and its heartbeat may be heard for the first time the development from this point
on is that of extensive growth and refinement of individual organs and tissues.
Within the uterus the child usually occupies this position here is the billable
cord which passes from the child to the placenta commonly called the afterbirth
it is through this cord and placenta
that nourishment is carried to the growing fetus from the first month to the day of
its birth.
In a closer view of this mechanism we see
that no direct connection exists between the circulatory system of the mother
and that of the child.
Food is carried in the mother's blood to the uterine wall the placenta carries the
bloodstream of the child to close contact with the uterine wall
by arse mosts food is carried across the spongy tissue from the mother to the child
while waste from the child are similarly path across to the bloodstream of the
mother. This is the only contact between mother and child.
There is no common blood stream as this break one lives off as a matter of fact all
of the child's blood was formed within its own developing body at full term nine
months the child has reached an average length of about eighteen inches
and an average weight of about six to eight pounds at this stage the child is a
completely developed living organism
and the better you understand all of these facts.
The better you will be prepared to discharge one of the greatest responsibilities
of parenthood the intelligent education of your child to the fact of human
reproduction.
Why do you have to say well today most babies are born in hospitals.
Loam birth mothers is bringing babies into the we're only careful attention in the
hospital is the best place for that right.
Dad But you also know
that an expectant mother requires medical attention from the very beginning of
pregnancy because from this time on marked physical changes take place in our body.
Here we see first the normal female figure showing the uterus
and vagina. As pregnancy continues.
The uterus becomes more distended with corresponding changes in body contour
the stomach intestines the liver
and other organs are pushed out of the normal position posture is changed.
You can also see the enlargement of the breast in preparation for feeding the
infants. Yet as marked as these physical changes appear they are only temporary.
Shortly after childbirth. Most of them will disappear.
Here in a closer view we see the fully developed child just before birth in the
usual position for deliberate.
Here is the uterus greatly extended the cervix still on old
and the vagina
and the pelvic girdle formed by the hip bone through which the child will pass.
All
but the pelvic girdle are tissues which can easily stretch during previous examination
the position has been formed in cells of the position of the child
and the size of the pelvis.
And now he awaits the expected body action.
This begins with rhythmic contractions of the uterus.
These contractions started long intervals.
But gradually become regular the greatest contractions occur at the upper end of
the uterus. So the pressure is directed towards the cervix as the.
Contractions become even more frequent the cervix open.
For the Jainas stretches to permit passage of the child
and aided by contractions of the abdominal muscles the child is brought into the
world in a normal manner.
This plan is a story of reproduction a story which any parent should fully
understand not only to ensure the arrival of a healthy child
but also to cope with the sensitive minds of children your children throughout
successive stages in their constant search for knowledge on your answers may well
depend the physical and emotional health of future generations.
I just have little if you have twin boys
or where you mean just thinking of all the questions you're going to
have to answer.
