#1 digestive review Flashcards
(17 cards)
alimentary canal Gi tract
vs accessory organ
alimentary - oral cavity , mouth esophagus stomach small intestine & large intestine
accessory organs - teeth , tongue , salivary gland , liver & gallbladder pancreas .
function digestion
ingest , food - break down
fluid - electrolytes acid - base homeostasis
ingestion - bring food & water in months
propulsion- via peristalsis
digestion - mechanical & chemical
absorption - through wall - alimentary canal & lymph
eliminate waste
salivary amylase trigger what
trigger the CHO DIGESTION ( happen in mouth )
goes in S.I
in the pancreatic amylase break down to disaccharide then monosaccharide
then absorb to bloodstream
function of saliva
mechanical & chemical digestion
& dissolve food in saliva
moistening lubricanting & cleansing oral
what is deglutition
swallowing
pepsinogen in stomach
release by chiefs cell (hCl activate it ; release by parietal cell )
turn to pepsin (start protein digestion)
trypsin small intestines
continue protein digestion
trypsinogen release by pancreas activate in small intestine to trypsin
chymotrypsinogen release-by pancreas’s > activate in small intestine to chymotrypsin
peptidase by small intestine & what happen trysin & chymotrysin peptidase
finish breaking peptides into amino acids & get absorb by blood in small intestine
fats - bile
where it’s store , produce by & whre it break down & what it do
bile > store in gallbladder release by liver
work in small intestine to emulsifies fats into smaller
fats - pancreatic lipase
release by pancreas ( produce by it )
release in small intestine
break triglycerides into fatty acid +glycerol
organ in order
mouth >pharynx > esophagus > stomach > small intestine > accessory organs (liver gallbladder pancreas)> large intestine > rectum anus
small intestine organization
duodenum - chemical digestion happen here
jejunum most absorption happens
ileum - last sec , absorb remaining nutrients & go to cecum ( large intestine )
large intestine
mostly water reabsorption
cecum - first part connect to ileum
ascending colon
transverse colon
descending colon
sigmoid -s shape lead to rectum
rectum - store feces
anus -exit
bile store where & where it’s made
gallbladder & made by liver
cck trigger to release bile
appendix attach to
cecum
protein break down begin in
stomach w pepsin
pancrease secrete
amylase trysin chymotrysin
