hormones of abdomen

gastric

stomach - stretching walls of stomach → increase secretion of HCL

cholecystokinin

small intestine - fatty acids and peptides → stimulates pancreatic enzyme secretion, pancreatic bicarbonate secretion, gallbladder contraction, growth of exocrine pancreas, and inhibits gastric emptying

gherkin

stomach - empty stomach → stimulates appetite, increases food intake, promotes fat storage

intrinsic factor

parietal cells of stomach - necessary for B12 absorption

HCL

parietal cells of stomach

secretin

duodenum - acidity of chyme → decreases gastric secretion, stimulates the pancreas secretion of bicarbonate ions

pepsin

stomach - presence of pepsi oven → HCL and pepsin converts pepsinogen to pepsin (protein enzyme)

GIP

duodenum - fat and glucose levels → stimulates insulin release, inhibits gastric acid secretion

motilin

duodenum - fatty acids → stimulates gastric and intestinal motility

pancreatic amylase

pancreas - digestion in small intestine → breakdown of carbohydrates

nuclease

pancreas - digestion in small intestine → breakdown of nucleic acids

trypsin

pancreas - digestion in small intestine → breakdown of proteins

peptidase

pancreas - digestion in small intestine → breakdown amino acids

gastric lipase

stomach - digestion in small intestine → breakdown of lipids
