This programme demonstrates the working of the digestive system through Dr von Hagen's dissection of a woman's body.
He demonstrates the passage of a mouthful of food down the oesophagus and removes the entire abdominal block from the tongue all the way to the anus and, after dissecting all the organs along the digestive tract, unravels it to its full length of seven metres.
