Document Summary
Bios 2400 - chapter 18 - digestive physiology. 18. 2 regulation of gi function: what is regulated, all aspects of the gi processes, regulated by. In general, the signals are: neural (sympathetic and parasympathetic (main), hormonal, specifically, the controls and systems are, the long & short reflexes, gi peptide reflexes, the autonomous function of the enteric nervous system (ens, neural regulation, long reflexes. ) production from pancreas to: cholecystokinin (cck) buffer acidic chyme, secreted in response to lipids and slows gastric motility and gastric acid secretion; bulk of lipids digested here, acts hormonally on the hypothalamus, has to do with lipase. Ileocecal valve controls chyme entrance into colon: relaxes in sequence with intestinal peristalsis as well as when gastric emptying starts (gastrocolic reflex, cck, serotonin and gastrin are potential initiators of the gastrocolic reflex, defecation reflex. 18. 4 absorption: carbohydrate digestion occurs for monosaccharide, glucose, fructose, galactose, protein absorption.
