På vilka sätt utsöndras bilirubin?
Det bildas då bilirubin som avfallsprodukt när det järninnehållande hemoglobinet i de röda blodkropparna bryts ner. Det gulfärgade ämnet utsöndras från levern till gallan och därefter vidare till tarmen där bakterier bryter ner det ytterligare till ett mer brunfärgat ämne.
Vart bryts bilirubin ner?
Bilirubinet tas om hand av levern och utsöndras via gallan till tarmarna. Här bryts bilirubinet ner ytterligare av bakterier och bildar det bruna färgämne som ger avföringen dess färg. Vid stopp i gallgångarna kommer ej något bilirubin ut i tarmen och avföringen blir vit & kittfärgad.

Elevated or unusually high levels of bilirubin in the urine can cause jaundice due to the yellowish pigment of bilirubin, among other more serious health problems.
