The article presents a brief overview of the responses of the GI tract and
its associated pancreatic and biliary systems to a meal. These responses are
specifically regulated by complex and interacting neural, hormonal, and
parcrine pathways. Stimuli for various responses are multiple and include
anticipation, senses of olfaction, taste and hearing, and chemical and
mechanical stimuli of meal constituents. The overall result of the integrated
response is assimilation of nutrients and elimination of wastes from the GI
tract.
