jaundice Flashcards
jaundice is caused by
raised bilirubin
bilirubin is derived from
breakdown of haemoglobin in the spleen
how is bilirubin transported
bound to albumin
where is bilirubin conjugated
liver
what is the bilirubin conjugated to
bilirubin glucuronide
how does bilirubin leave the liver
excreted via the bile duct into the small intestine in bile
what happens to conjugated bilirubin in the terminal ileum
converted to urobilinogen and excreted in the faeces or absorbed by kidenys and excreted
what is urobiligen excreted in the stool as
stercobilinogen
where does bilirubin become urobiligen
terminal ileum
three categories of jaundice
Haemolytic jaundice
Congenital hyperbilirubinaemias
Cholestatic jaundice
Cholestatic jaundice
failure of bile secretion by the liver or bile duct obstruction
Haemolytic jaundice principal
Increased breakdown of red blood cells leads to increased production of bilirubin
what is raised in haemolytic jaundice
raised serum unconjugated bilirubin
most common congenital hyperbilirubinaemia
gilberts
what does bilirubinget conjugated to
glucuronic acid
