The may 2011 issue of the German magazine “Guter Rat” (good advice) features – among other topics – the human digestive system. A four-page article includes a summary of the famous Fritz Kahn illustration “Man as Industrial Palace”: “ … Chunks of raw material are thrown into the mouth, where grinding wheels pulverize the chunks, and a worker operates the saliva injectors. Then the mash slides down a thick pipe to the next level of digestion. Kahn’s depiction is based in reality. … Simplified, digestion can be seen as conveyor belt. Each station is responsible for a specific step in the digestion process.” The article refers to the monograph “Fritz Kahn – Man Machine” and this website. – “Guter Rat” is a monthly publication of Hubert Burda Media with a circulation of 250,000 copies.
