The Development of a Fetus in it’s Mothers Womb
Nine months may seem like a long time, but its
short when you realize all that mother and baby have to do. Most women
undergo a change in feeling, appearance, mood, and energy. In the end when
the mother meets the baby that has been growing inside her, pregnancy will
make sense. For now sit back and relax, pregnancy is quite a ride.
The first trimester is from conception to
fourteen weeks. In the first month a woman usually has no idea that she is
expecting. The uterus formed a bed of tissue, and in hours after
fertilization, gender, eye color, and texture of the baby’s hair are set. The
fertilized egg will divide into cells as it flows through the fallopian tube.
Then it settles in the uterus, where it will stay for the next thirty-six
weeks or so. Human Chorionic Gonadotropin, is produced, the hormone that make
a pregnancy test positive.
In month two the placenta the placenta and the
umbilical cord are functioning. The amniotic sac has formed around the
embryo. Its poppy-seed-sized heart is beating, and other major organs are
In month three the embryo is now called a
fetus. The doctor will begin to pick up rapid heartbeat. By twelve to
fourteen weeks the baby will grow to be three to four inches in length. The
baby will also weight a little more than an ounce. Bones will being to form,
fingernails and toenails will grow, and the gums will have tiny buds
beginning to spout.
The second trimester is from fourteen weeks to
twenty-eight weeks. In month four the fetus if fully formed, although it is
out of proportion. The skin is covered with tiny hair called lanugo. The
heartbeat gets stronger and the fetus sleeps, kicks, swallows, and even
urinates. Most women may be able to feel their babies moving.
In month five the baby should be moving very
rapidly. It has grown to be about a pound now and twelve inches long. The
baby also begins practicing breathing. The fetus can even hear.
In the sixth month the baby’s movements are
much stronger and happening more frequently. The fetus usually sleeps during
the day and is awake and active during the night. Most women find this
leaving them restless, and try settling down often during the
The third trimester is from twenty-eight weeks
to forty weeks. In month seven the fetus is growing, growing, growing! The
fetus starts making faces, crying, kicking, and elbowing its mother. Most
women notice that the baby has begun really hurting their ribs, this means
that the baby is head down and will stay that way until they deliver.
In the eighth month the baby will gain most of
its birth weight. This causes the uterus to grow 1,000 times it original
size! The head, foot, and elbow are easily found. If the gender is male his
testes are beginning to descend. The bones are getting strong, but the head
will remain soft so the baby can pass through that birth canal easily.
In the ninth month the lightening stage begins.
This means that the baby slips down into the position for birth. Labor starts
soon after, but because everybody’s labor is not the same it will take as
long as it needs before the baby is born.
Being pregnant is not as bas as it may sound.
Although it takes nine months the result of the baby will bring much joy. The
nine months of pregnancy will soon be forgotten.
