GI Physiology

  • The basic function of the Gastrointestinal tract is to absorb the nutrients, electrolytes, and water within ingested foods and liquids. To do so, the GI tract must propel ingested substances through different functional segments which are specialized in transport, digestion, and absorption. These processes are highly regulated through both nervous and endocrine mechanisms.
