This program uncovers the secret life of our digestive tract in an eye-opening and detailed exploration of the side of the body we normally never get to see. Using the latest in medical imagery and a tiny state of the art camera "pill" that he swallows at the start of the film, Michael Mosley takes viewers on a remarkable journey through his own internal system. At each stage he talks to medical experts and explains the amazing functions that happen without our conscious effort. This is one of the most fundamental parts of our bodies, controlled by its own nervous system and automatically providing our energy, water and nutrients; yet unless we get sick, we rarely think about what it's doing.
