Final digestive Flashcards
Teeth
incisors, cuspids, premolar, molar; mastication
tongue
frenulum anchors to bottom of mouth; glutination; bolus->pharynx
Salivary glands
amylase, submandibular, sublingual, parotid
Esophagus
passes through diaphragm to stomach- gastroesophageal sphincter prevent acid reflux GERD
Top outer curve of stomach
fundus
Bottom outward curve of stomach
great curvature
Top inward curve of stomach
lesser curvature
Small top outward curve
Pylorus
Region close to pyloric sphincter
Pyloric Region
Connects pylorus to duodenum
Pyloric sphincter
Layer of stomach that churns fewd
3rd layer- oblique muscles
Secretory cells in stomach
-mucous (thin)
-chief pepsin=protease
-parietal-HCl=break protein down to digest/absorb
make up gastric juice^^
-mucous(thick) protect stomach from HCl-ulcers
Pacreatic digestive enzymes
lipase, protease, amylase, disaccharidoses
other 2 sections of small intestine
jejunum-> ileum (ileocecal valve) -> cecum (large instestine)
Large intestine
Ileocecal valve-> anus;ascending (hepatic flexure) transverse (splenic flexure) descending , sigmoid colon; absorbs water; contains e coli; 30% of feces is bacteria
Liver (hepatic) accessory organ
Largest organ; partially protected by ribs; produces bile; hepatic portal circulation-process nutrients
Hepatic portal circulation
blood collected from hepatic artery and portal vein taken through central vein; bile produced by liver cells->bile ducts-> stored in gall bladder
Where the pancreatic duct and the common bile duct meet
Ampulla of Vater
CCK
presence of chyme=duodenum secretes cck->stimulates release of bile and digestive/alkaline secretion from pancreas
Stones in gallbladder
Cholecystitis
Pancreas
(exocrine) ->pancreatic duct->pancreatic juice-has enzymes and alkaline secretions
Acid in duodenum stimulates release of ____ from duodenal walls
secretin which causes pancreas to release bicarbonate
Digestive enzymes are secreted by
Acinar cells in pancreas
carbs
proteins
fat
carbs-amylase
proteins-proteases- trypsin and chymotrypsin
fat-lipase
secreted inactive form; activated in duodenum, work best in alkaline ph
