So lets come to the title of this post " Fetal Development Stages". The explanation is going to be in pictograms with little bit of description under the pictures. Here it goes...

Sperm

The Egg Cell

Sperm meets the Egg Cell

Sperms are contacting with the egg cell to break down the walls.

The "Winning Sperm"

The sperm 5 - 6 days.The clump has developed into a blastocyst,
containing many more cells and has entered the womb.

8 days. The human embryo is attached to a wall of the uterus.

The brain starts to develop in the human embryo.

24 days. The one-month-old embryo has no skeleton yet.
There is only a heart that starts beating on the 18th day.

4 weeks

5 weeks: Approximately 9mm.
You can distinguish the face with holes for eyes, nostrils and mouth.

40 days: Embryonic cells from the placenta.
This organ connects the embryo to the uterine wall allowing nutrient uptake,
waste elimination and gas exchange via the woman's blood supply.

8th weeks. The rapidly-growing embryo is well protected in the foetal sac.

10 weeks: The eyelids are semi-shut. They will close completely in a few days.

16 weeks. The foetus uses its hands to explore its own body and its surroundings.

The skeleton consists mainly of flexible cartridge.
 A network of blood vessels is visible through the thin skin.

18 weeks: Approximately 14 cm.
The foetus can now perceive sounds from the outside world.

19 weeks: Developments of fingernails

20 weeks: Approximately 20 cm.

 Woolly hair, known as lanugo, covers the entire head.

24 weeks

26 weeks

6 months. There are still 8 - 10 weeks ahead,
so the little human is getting ready to leave the uterus.
It turns upside down because it will be easier to get out this way.

36 weeks. The child will see the world in 4 weeks.
