  1. DIGESTIVE CELLS OF THE STOMACH

  2. PARIETAL CELLS • OFTEN BINUCLEATED • PUMP H⁺ IONS INTO LUMEN • LIE IN THE STOMACH WALL http://highered.mcgraw-hill.com/sites/0072943696/student_view0/chapter16/animation__hydrochloric_acid_production____of_the_stomach.html

  3. CHIEF CELLS • PRODUCE TRYPSIN & CHYMOTRYPSIN • ALSO CALLED PEPTIC CELLS • RELEASE PEPSIN & RENNIN • SECRETES GASTRIC JUICES THAT HELP DIGEST TRIGLYCERIDES TO FREE FATTY ACIDS & DI-GLYCERIDES • IN CELLS OF STOMACH WALLS

  4. NECK CELLS • MAKE MUCOUS • LOCATED IN GASTRIC PITS OF STOMACH LINING

  5. GASTRIC GLANDS • ALSO CALLED FUNDIC GLANDS • PRODUCE PROTEASES • DRAIN INTO THE MUCOUS TO ENTER LUMEN
