The Digestive System
As food enters the intestines, it's still very acid, because of the stumach acid. The acid is neutralized by flushing the intestines with a bicorbonate flush. This flush is released from the pancreas and enters the duodenum (a part of the small intestines). This flush also consists of specific enzymes, which are neccessary to digest carbohydrates, proteins and fats. The flushing action of the pancreas is triggered by a specific hormone, which is called secretin.

Secretin-type: No Secretin Release
A child lacking the ability to release secretin will have a multi-pronged attack on the digestive system. First, the unneutralized stomach acid will severely damage the intestine. Second, there will be a deficiency of digestive enzymes and bile to process food.
