Good percentage of food can be pre-digested by alimentary enzymes in the stomach before reaching the small intestine, where the pancreas secretes its own enzymes for proteins, starches and fats at the level of duodenum. By virtue of this bio x4 mechanism, if it is not properly pre-digested food the pancreas increases its activities in order to "recruit" enzymes from the entire body, ending soon under stress. The text of Gray's Anatomy quotes Dr. Walther B.Cannon, an authority on the subject, to say that the stomach "... consists of two physiologically distinct parts: the cardiac cavity portion and a food-gathering in which the salivary digestion continues; pyloric portion is the active site of gastric digestion. There are peristaltic waves in the cardiac region. " There is a law called "Adaptation secretive of Digestive Enzymes" which states that the greater the load being acquitted in digestion by exogenous
