AB The  digestive  or  gastrointestinal  system  is  roughly  defined  as  the  anatomical  component  from  the  mouth  to  the  anus,  including  organs  responsible  for  transit,  mechanical  breakdown,  digestion  and  absorption  of  foodstuffs,  as  well  as  the  efficient  elimination  of  solid  waste.  Included  are  the  mouth  and  dentitia,  pharynx  and  esophagus,  stomach,  small  intestine,  liver,  gall  bladder,  pancreas,  large  intestine,  rectum,  and  anus.  As  with  the  complex  integration  and  control  of  metabolism,  the  digestive  system  is,  itself,  under  the  influence  of  neurological  and  hormonal  regulation  that  both  activates  and  inhibits  many  of  its  complex  actions.  Most  of  these  complex  actions  are,  themselves,  simple  biochemical  processes  of  proteins,  carbohydrates,  lipids,  and  nucleosides/nucleotides  to  include  enzyme  reactions  with  associated  activating  and  inhibitory  molecules,  membrane-spanning  protein  channels,  and  pumps  all  leading  to  the  production  and  storage  of  energy  and  essential  building  blocks  for  current  or  future  use.
