Spallanzani's digestion experiment. Historical artwork of an experiment on digestion carried out by the Italian biologist Lazzaro Spallanzani (1729-1799). Spallanzani fed birds with food in perforated containers,which were recovered by pulling on an attached string (seen here). Spallanzani concluded that a major part of digestion is the action of fluids in the stomach,which he named gastric juices. Spallanzani's experiments helped to overturn Galen's theory that digestion was a form of cooking due to the heat of the stomach | |
