Normal Liver Function Flashcards
what are the normal functions of liver?
synthetic – protein synthesis and coagulation proteins
metabolic – fat, carbs and protein metabolism
excretory – bilirubin and bile acid metabolism
detoxification
proteins in plasma
6-8 mg/dl
function of albumin
maintain osmotic pressure
transfer water in soluble substance
hypoalbuminemia causes
edema
albumin deficiency leads to
chronic liver disease
malnutrition
nephrotic syndrome
protein losing enteropathy
coagulation factors secreted
5,7,9,10,12
liver is storage site for
glycogen
liver damages leads to
hypoglycemia
increased ammonia levels lead to
hepatic encephalopathy
how bilirubin metabolism takes place
biliverdin is formed
reduced to bilirubin
initially unconjugated and water soluble
transported to liver attached to albumin
hyperbilirubinemia causes
jaundice
how is bilirubin excreted
conjugated bilirubin enters the intestine
hydrolyzed by bacterial enzymes
reduced to urobilinogen
excreted in stool as stercobilinogen
remaining absorbed in terminal ileum
urobilinogen binds to albumin and then into circulation
and excreted in urine by kidney
bile aid metabolism
synthesized in hepatocytes
excreted in bile and pass into duodenum
cause fat solubilization
decreased bile salts cause
pruritus – itching
bleeding disorders– vit. K def
steatorrhea –fatty stool
increased level of insulin, glucagon, estrogen, growth hormone, glucocorticoids and parathyroid cause
gynecomastia
