Inside the human body. Part 1, Creation.

The first in a four-part series, presented by Michael Mosley, in which CGI footage is used to show the workings of the human body. In this part, we see the process of human biological creation. State-of-the-art graphics show how millions of sperm race towards the egg and the best is selected by the female egg. We see a body beginning to self-assemble and the process of how a human face comes together is shown. We meet a couple who have triplets, a woman about to have her sixteenth child and the oldest conjoined twins in the world.
