The other is as though
everything is a miracle.”

Objectives:
 To gain a better understanding of what
happens after fertilization.
 To be able to identify the three stages of
pregnancy and what occurs during each
one.
 To better understand the process of fetal
development.
 To identify the pros and cons of having a
baby now and/or in the future
Seat Partner Activity
1.Make a list of the pros and cons of
having a baby as a teenager
2.Make a list of the pros and cons of
having a baby as an “adult.”
3.When do you believe is the right
time to have a baby?
“In the best of all possible worlds,
childbirth enriches a relationship. In
the worst, it harms it. No matter how
good their relationship is, most
couples find that having a baby
challenges their relationship.”
Let’s review fertilization…
Fertilization defined:
The joining of an ovum (an egg)
and a sperm.
This takes place in the fallopian
tubes.
To get a clear picture,
please watch this amazing video…
But what happens after that?
A whole heck of a lot...
Basically, there are three stages of prenatal development:
1. Germinal Stage
2. Embryonic Stage
3. Fetal Stage
And, pregnancy is broken into three trimesters.
1st Trimester- From Fertilization through week 12
2nd Trimester- Weeks 13-27
3rd Trimester- Weeks 28-40
Fetal Development
Read the article entitled Prenatal
Development: An in-depth look and
answer the questions on the
corresponding worksheet.
Once we finish our
worksheet, we will view
another brief video.
Terms to be familiar with…
 Fetus-an unborn, developing mammal,
after the embryonic stage.
 Placenta- the organ formed in the lining of
the uterus by the union of the uterine
mucous membrane with the membranes
of the fetus, that provides for the
nourishment of the fetus and the
elimination of its waste products.
 Umbilical cord- a cord connecting the
embryo or fetus with the placenta of the
mother and transporting nourishment
from the mother and wastes from the
fetus.
What
exactly is
childbirth?
The human act or
process of giving
birth; also known
as labor.
Labor, by definition
means physical or
mental exertion,
especially when
difficult or
exhausting; work.
Some facts and statistics related
to childbirth:
 More than FOUR million babies are born each year in the
United States.
 The most popular day for babies to be born is
Wednesday; Sunday is the least common day.
 With about 1,049 male babies for every 1,000 female
babies in 2006, boys are keeping the edge in a ratio
that's stayed about the same over the past 60 years.
 Some women deliver babies “naturally,” or without the
help of pain medication.
There are two different types of
deliveries:
Vaginal Births
Cesarean Sections
(C-Section)
The human act or process
of giving birth via vaginal
canal.
A surgical procedure in
which incisions are made
through a woman's
abdomen and uterus to
deliver her baby.
Post-Delivery of Baby
Immediately following the birth of the baby, doctors
and nurses perform an examination of the baby and
conduct various tests on the baby to check his or her
wellness.
 One of the most important tests conducted is:
Apgar Test- a numerical measure of the physical
health of a newborn infant derived by evaluating
heart rate, muscle tone, respiratory effort,
response to stimulation, skin color, and other
physiological indicators.
And then what?
Conclusion
 From fertilization until childbirth, many changes
take place inside the uterus.
 The three stages of pregnancy include:
 The Germinal Stage
 The Embryonic Stage
 The Fetal Stage
All three stages are critical during this
process.
 The process of giving birth is an arduous task; that
is why it is called labor.
