ingestion
esophagus
muscular contraction propel food
cardiac sphincter
prevents back flow of stomach contents into esophagus
cardia
fundus
body
pylorus
regions that comprise organ that churns chyme
rugae
folds present when stomach is empty
digestion
mucous neck cells
secrete mucus prevents stomach from digesting itself
chief cells
secretes inactive enzyme pepsinogen
digestion
parietal cells
secret hydrochloric acid help convert pepsinogen into pepsin
G cells
secrete gastrin (a hormone that stimulates gastric juice secretion n promotes motility
pyloric sphincter
controls flow of chyme into duodenum
acini
secretes pancreatic juice
islets of Langerhan
secretes insulin
other
pancreatic duct
unites with common bile duct to form the common duct
liver
filters n detoxifies blood, secretes bile, metabolizes macromolecules
gall bladder
stores n concentrate bile
digestion
cystic duct
joins common hepatic duct to become the common bile duct
duodenum
10 in
shortest, common bile duct empties here
jejunum
3ft
digestion, absorption
ileum
6 ft joins w/ large intestine
microvilli
projections of the plasma membrane that increase surface area
circular folds
cause chyme to spiral
absorption
intestinal glands
secrete intestinal juice
absorption
ileocecal sphincter
control flow btw small n large intestine
cecum
appendix is attached here
