Michael Mosley embarks on an astonishing voyage through the world's most complex organism--you.

Inside The Human Body takes us deep under our skin where we are dwarfed by even the smallest cell, where blood vessels become vast cathedrals and the tiniest cluster of cilia becomes an expansive forest.

Our body’s almost infinite ability to adapt and surprise is illustrated by the stories of remarkable characters whose bodies allow them to do amazing things, live in incredible places and push their physiology to the limits. Spectacular photography shows human behaviour in super slow motion, revealing elements of ourselves that we are completely unaware of.
