Digestive System Flashcards
begins in the mouth with chemical and mechanical digestion, structures starts with oral cavity and ends at the anus, shares respiratory structures
digestive system
3 salivary glands
parotid, submandibular, sublingual
mainly made out of water
saliva
2 functions of the tongue
speech + swallowing and moving food for chewing (mastication)
3 basic enzymes
amylase, protease, lipase
the salivary enzymes
amylase and lipase
digests starch and carbohydrates
amylase
digests lipids/fats
lipase
4 walls of the stomach in correct sequence (innermost to outermost)
mucosa, submucosa, muscularis, serosa
releases HCL
parietal cells
what would happen if there was a lack of chief cells
less gastrin and pepsinogen
why the stomach doesn’t auto digest
mucus alkaline membrane that protects the stomach and pepsinogen is inactive
passes pancreatic juice to duodenum, known as the all secreter
pancreas
releases all active digestive enzymes (amylase, protease, lipase, trypsin, chymotrypsin, and carboxypeptidase) and stimulates pancreas to release pancreatic juices
CCK
hormone(s) released by the pancreas
protease, insulin, lipase, amylase
hormone(s) not released by the pancreas
gastrin
