A long journey in 8 episodes to discover the human body, with Piero Angela who closely observes our organism, focusing each time on a theme: the eye, the ear, taste and smell, the stomach and the intestine, liver, bones, lungs and heart. How does our "wonder machine" work? To make each explanation direct and clear, the program uses films, animations and photographs developed with the scanning electron microscope.
