Even weeks before a woman finds out that she is currently pregnant, there are numerous important life building developments taking place within her womb. A talented Swedish photographer Lennart Nilsson spent hard working 12 years taking some incredible photographs of each and every single stage a cell of human embryo travels through in its entire journey scratch from fertilization to the birth of a baby. These amazing and beautiful pictures were taken with conventional cameras with macro lenses, an endoscope, & a scanning electron microscope. He started this in year 1965, & magnified the images by hundreds of thousands.

The absolutely mesmerizing results are featured below just for all of us to marvel at.. (Photos + Video)

#. At 4 weeks.

#. At 5 weeks, human embryo is approximately 9 mm. Its face is now distinguishable with holes for eyes, nostrils, & mouth.

#. At 40 days. Embryonic cells have formed placenta, which connects the embryo to uterine wall allowing nutrient uptake, waste elimination, and gas exchange via mother’s blood supply.

#. At 8 weeks, the rapidly growing embryo is now well-protected in embryonic sac.

#. At 10 weeks. The eyelids are almost semi-shut, and will close completely in just a few days.

#. At 16 weeks. The foetus uses its hands to explore its own body first time and its surroundings.

#. The skeleton at this stage consists mainly of the flexible cartilage. You can clearly see a network of blood vessels through thin skin.

#. At 18 weeks. The foetus is approximately 14 cm & can now perceive sounds from its surrounding outside world.

#. At 19 weeks.

#. At 20 weeks. Foetus is now approximately 20 cm. We will able to see woolly hair, known as lanugo, covering the entire head.

#. At 24 weeks.

#. At 26 weeks.

#. At 6 months. Baby is now preparing to leave uterus. It turns upside down because it’ll be easier to get out this way.
