Our body is a fascinating factory on two legs. Together with the children Pim and Polly, we take a tour through this factory - from the control room at the top, through the acid bath of the stomach, and the rollercoaster ride through the intestines, all the way down to the gatekeepers of the rectum. However, due to overload and constipation, the factory is on the brink of shutting down. Pim and Polly are determined to save it. Using the image of a factory with all its departments and machines, this book 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.
