WebBiliary Excretion. Biliary 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. WebViews. Liver function tests, often known as liver chemistries, measure the levels of proteins, liver enzymes, and bilirubin in your blood to assist in evaluating evaluation of the health of your liver.
