How bilirubin is excreted
WebBiliary excretion involves active secretion of drug molecules or their metabolites from hepatocytes into the bile. The bile then transports the drugs to the gut, where the drugs are excreted. The transport process is similar to those described for renal tubular secretion. The efficiency of biliary excretion is quite variable. WebBilirubin passes through the liver and is eventually excreted out of the body. Higher than normal levels of bilirubin may indicate different types of liver or bile duct problems. Occasionally, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells (hemolysis). How does bilirubin end up in urine?
