Our body is a fascinating factory on two legs. Together with the children Pim and Polly, we take a tour of this factory - from the control room at the top, through the stomach's acid bath and the rollercoaster ride through the intestines, down to the gatekeepers of the rectum. However, due to overload and constipation, the factory is on the verge of shutting down. Pim and Polly are determined to save it. Using the image of a factory with all its departments and machines, this description explains what happens during digestion with many fun illustrations and information boxes. From the bite in the mouth to the sausage in the toilet - an exciting tour of our digestive system.
