The document describes the development of an embryo from the first few weeks in the womb through full term pregnancy over 40 weeks. It explains how the embryo is initially nourished by the yolk sac, then the umbilical cord, and develops limbs at 16 weeks while the eyes are still closed. Modern 4D ultrasound allows viewing facial expressions at 24 weeks when the lungs are not fully formed but survival outside the womb is possible. Movement increases as the space is sensed, and dreaming begins. Birth is a traumatic experience for the baby as well as the mother, but signals the miracle of the formation of human life in the womb.

In the womb

2. Ria slides
An embryo of few weeks inside the mothers womb.

3. Ria slides
It is in the beginning of its
development.
There is a long road ahead.

4. Ria slides
It is the first step of human development and at this stage it can be confused with
the embryo of dog or monkey.

5. Ria slides
It is connected to the vitelino bag that provides the nutrients that it needs in the
first weeks of life.

6. Ria slides
After about 8 weeks of gestation the vitelino bag loses its function.
The umbilical cord then starts to feed it with nutrients
provided from the mothers body.

7. Ria slides
While everything happens, it floats, calmly, in the uterus of its mother.

8. Ria slides
In 16th week of gestation it already has
developed the limbs.
The eyes are still closed, but the hands and the feet start to move
themselves, even though its mother does not perceive it yet.

9. Ria slides
Thanks to the ecografia 4D, you can see the features of the baby quite clearly,
even its faceial expressions.

10. Ria slides
At 24 weeks Only the lungs are not completely formed.
if it was born at this moment, it would have a good chance of survival.

11. Ria slides
At this stage It already moves the arms and the legs, it blinks the eyes, and it
sucks the fingers

12. Ria slides
It is becoming conscientious of
the space that surrounds it.

13. Ria slides
As with all embryos, it passes most of the time sleeping
It even dreams

14. Ria slides
Complete at nine months and is ready to be born.
In 40 weeks, what was one cell was changed into a human being.

15. Ria slides
The miracle of the formation of the life of a human being
in the womb is almost finished
In few days the lungs and the placenta will be put in charge to signal that the
hour of the childbirth has arrived.

16. Ria slides
The baby still sleeps, calm, in the womb of its mother.
It does not know that soon it will abandon the placidness of its "house" to pass
through one of the most traumatic experiences of its life: the birth.

17. Ria slides
Yes, because the childbirth is not
painful only for the mother.
It is also traumatic and stressful for the baby.

18. Ria slides
BUT IT IS THUS THAT IT HAPPENS
The MIRACLE Of LIFE

The images used in this pps are part of the set of documents produced for the National
Geographic Channel: En el Maternal Vientre. Are images gotten through a micron-
chamber introduced in the uterus of a gestante. Thanks to the modern photographic
techniques it is possible to follow the fascinating process of gestation of a baby. If it
