Get an inside view - You may be pretty familiar with what you look like from the outside, but in Guts presenter Michael Mosley gets up close and personal with his own digestive system to reveal what we look like inside. Guts uncovers the secret life of our digestive tract In an eye-opening and detailed exploration of a part 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, 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. Thanks to this fascinating documentary, that's all about to change. Guts is a BBC science documentary which allows viewers to explore the inner workings of our digestive systems.
