Document Summary
Also if you make corrections, please explain why/what was wrong in a comment so everyone knows!! Salivary amylase- breaks down a 1-4 glycosidic bonds, denatured by hcl in stomach. Esophagus- peristalsis- wavelike contractions to push food in gi, uses involuntary/voluntary movements pressure is regulated by neural and hormonal mechanisms- prone foods- chocolate, alcohol, peppermint, fat. Stomach- secreted 2 l a day of gastric juices, empties food within 3-5 hrs. Lower esophageal sphincter- when pressure drops food comes back up into esophagus, Gastric juice- water, electrolytes, hcl (denatures proteins, converts pepsinogen to pepsin and kills bacteria), bicarbonate, mucus. Enzymes- gastric lipase (hydrolyzes fatty acids from glycerols, Gastrin is secreted- releasing the gastric juices (si) signals secretin- Causes pancreas to secrete pancreatic enzymes and bicarbonates. At the same time . liver produces bile from chol, and stored in the gallbladder. bile to emulsify fat, form micelles and gets secreted into duodenum. Small intestine - enteroendocrine cells secrete cck signaling gallbladder to produce.
