How to find a clip from BBC The Human Body documentary?

I am looking to find a clip from the series of 'The Human Body' documentary of BBC. In that clip, a camera is pushed inside a vagina in order to show exactly what happens when people have sex, as well as looking at factors like arousal and how it all works. Any direct link for download of this clip? Thanks. show more I am looking to find a clip from the series of 'The Human Body' documentary of BBC.
