Organ Region of the Organ Substances FunctionPancreas Acinar cells Amylase (enzyme) Breaks down starch and carbohydrates into glucose
Acinar cells Lipase (enzyme) Breaks down fat into fatty acids
Acinar cellsProtease enzymes (trypsin,
chymotrypsin, carboxypeptidase)Breaks down proteins into amino acids and also kills intestinal parasites and bacteria
Acinar cells Bicarbonate (not an enzyme) Raises pH in duodenum
Islet of Langerhans;
Alpha cells glucagon (hormone)
Causes glycogenolysis, the process which breaks down glycogen into glucose to raise blood glucose. Also causes gluconeogenesis to make new glucose molecules
Islet of Langerhans;
Beta cells insulin (hormone)Removes glucose in bloodstream and brings it into cells. Lowers blood glucose levels.
Islet of Langerhans;
Delta cells Somatostatin (hormone) Inhibits gastrin, insulin, and glucagon (inhibits digestive system)
Liver Bile (a detergent) Emulsifies fat Lipase Breaks down fat
Salivary glands Amylase (enzyme) Breaks down starch and carbohydrates into glucose Lipase Breaks down fat
Stomach Mucous (not an enzyme) Protect the stomach liningProstaglandins (not an enzyme) Protect the stomach lining
Lipase Breaks down fat
Parietal cells HCl (not an enzyme) Allows Pepsinogen to be converted to pepsin, and it also kills bacteria
Parietal cells Intrinsic factor (not an enzyme)Allows Vit B12 to be absorbed, which is needed to make RBCs. Without it, you get megaloblastic (pernicous) anemia.
Chief cells Pepsinogen --> pepsin (enzyme) Breaks proteins into amino acids G cells Gastrin (hormone) Tells parietal cells to secrete HCl
Duodenum Secretin (hormone) Tells pancreas to secrete bicarbonate
CCK (hormone)Tells pancreas to secrete proteases and lipase, and tells gallbladder to release stored bile (stimulates fat and protein digestion)
Motilin (hormone) Initiates peristalsis and tells Chief cells to secrete pepsinogen
Maltase, Lactase, Sucrase (enzymes) Break down complex carbohydrates into glucose
K cells GIP (hormone)Tells pancreas to release insulin and also causes fat to be broken down into fatty acids
