FECALYSIS Flashcards
faex meaning
residue
newborn’s first feces
meconium
study of feces
scatology or coprology
leads to excessive gas production
lactose intolerance
produces strong odor and flatus
bacterial metabolism
major site for final breakdown and reabsorption of compounds
small intestine
what are the digestive enzymes
trypsin
chymotrypsin
lipase
amino peptidase
lipase
value of increased daily stool
above 200g
increased liquidity and frequency of more than?
3x a day
major mechanism
secretory
osmotic intestinal
hypermotiliy
bacterial, viral and protozoan infection produces increased
secretion of water and electrolytes
secretory diarrhea usually caused by an organism that produces toxin that stimulates what enzyme?
adenylase cyclase enzyme
this enzyme leads to crampy diarrhea and secretion of interstitial fluid
adenylase cyclase enzyme
secretory diarrhea is characterized as
watery
voluminous
no rbc, wbc, and mucus
causative agents of secretory diarrhea
vibrio cholerae
etec (travelers diarrhea)
giardia lamblia
diarrhea caused by bacteria
invasive diarrhea
invasive organisms destroys what
mucosal lining of intestines
this destruction caused by invasive bacterias produces what
pus
blood
mucus
stool may contain what in invasive diarrhea
wbc
rbc
specks of mucus
organism
patients with invasive diarrhea experience what?
tenesmus
invasive diarrhea causative agents
shigella dysenteriae
entamoeba histolytica
eiec
campylobacter jejuni
yersinia enterocolitica
incomplete breakdown or reabsorbtion of food presents increased fecal material to the large intestine, resulting in the retention of water and electrolytes in the large intestine
osmotic diarrhea
usually caused by inefficient reabsorption of an osmotic substance due to an enzyme deficiency
osmotic diarrhea
osmotic diarrhea is characterized as?
watery
gaseous
no wbc, rbc and mucus
substances that are not reabsorbed in osmotic diarrhea
lactose
fat globules
muscle fibers
causative agent of osmotic diarrhea
lactose intolerance
pancreatic insufficiency
