Baby Development During Pregnancy
When a man
and women have sex the erect penis of the male is inserted into the vagina of
the female.Baby Development During Pregnancy.
The male are ejaculated into the vagina of the female the sperm cell of.If an egg cell has been released in the ovary at that time, it may get fertilized by the sperm and the women may become pregnant.
The Baby Development During Pregnancy develops in the women’s uterus for about 40 weeks till it is developed enough to be born.
Baby Development During Pregnancy
How does
fertilization occur.
After a man and women have had sex about 300 million sperm cells are present in the women’s vagina.
The sperms swim forward with the help of the tails with a common aim to fertilize the egg cell.
The egg cell ripens in the ovary of women only once a month certain hormones then trigger ovulation, in which the egg cell is released from the ovary in the fallopian tube.Fertilization occurs if the egg cell meets a sperm.
Doctor assumes that after ovulation an egg cell can be fertilized for a maximum of 12-24 hours.
A single sperm cell is enough to fertilize that egg cell.
What happens to the fertilized egg cell
A new life can start which the fusion of the sperm and the egg, which contains the genetic information of the father and the mother in equal parts.
On the way through the fallopian tube the egg lodged in the mucous membrane of the uterus, a special hollow muscle.
This has good blood supply and provides the egg cell with nutrients.After it is fixed in the uterus, the egg cell is called an embryo and development starts immediately.
What determines whether a baby is a boy or a girl
The sex of the baby is determined by the chromosomes.
All of us have 23 pairs of usually chromosomes .
They determine how our baby looks like and how it works that ate also the reason we resemble our parents.
In case of males and female the 23rd pair of chromosomes is different.In a women these are two x chromosomes in a man it is one.
The egg cell has an x chromosomes the sperm could have either an x or a y chromosomes.
If a sperm with a “Y” chooms fertilizes the egg then the chromosomes combinations fro the baby would be xy a boy if an x sperm fertilizes the egg, the result is everyone that the sex baby is determined by.
How does the body breathe in the uterus
A baby does
not need to breathe in the uterus.
Every things
that it needs for its growth is provided to it by its supply line: the umbilical
cord.
This card
connectects the of the mother, the foetus as the unborn through child is called gent nutrients and oxygen products of the fortes are thrown out into the blood
circulation of the mother and are excreted lye the mother.
After the
longer required and is cut off.
Why are some
babies disabled at birth
The causes
if disabilities are many and cannot always are explained.
We do know
that a lost of oxygen at birth can cause damaged of the brain.
If the
mother’s smokes of takes drugs during pregnancy it can have serious.
Consequences because the drug reaches the blood circulation of the child via
the umbilical cord.
Something’s
there may be genetic changes which may cause disabilities.
For instance
a change in the size chromosomes cause Down syndrome in the child.
It is
important to ensure that that people with disabilities are not discriminate against
in our society.
The egg cells
are the largest and the sperm cells is the smallest human cell.
Every minute
250 children are born in the world.
A baby at
birth weight more than 2 billion times the weight of the fertilized egg cells
which was what the body started as.
Amniotic sac
model.
Kneaded
beeswax an air balloon a water faucet a battery friend.
Do as follow
form a model resembling an embryo from the kneaded mass approx 5cm long and
place it inside than air balloon with the help of your partner.
Pull the
balloon over the water so that your embryo swims in the amniotic sac.
Tie the
torch what happens to your model when the moves of collides somewhere.
In the of
