Gastrin-hormones
|
Produced by stomach mucasa(g-cells)
target organ-stomach(parietal cells) small intestine Large intestine-Ileocecal valve Action-increases HCL secretion, stimulates gatric emptying, strimulates contraction of intestinal muscle, Relaxes ileocecal valve, stimulates mass movements Trigger mechanism-food partially digested proteins in stomach, chemical stimulation, acetylcholine released by nerve fibers |
