Gastrointestinal System Physiology

Gastointestinal System

             In Gastrointestinal System Physiology includes : Ingestion, Digestion , Absorption &                                                                                                         Excretion processes 

•  Ingestion    : The food enter into mouth is chewed by teeth is the process of Ingestion
•  Digestion   : In GI tract the food is digested by Chemical & Mechanical process & convert the                       large molecule into small molecules         
•  Absorption : In this process the the small molecules of nutrients that are necessary for the body                       are absorbed '
•  Excretion    : The waste product that are not digested & absorbed are excreted through the                                Anus
