Final answer:
Another name for post liver bilirubin is direct bilirubin. It is the water-soluble form of bilirubin that has been processed by the liver and is ready to be excreted in bile.
Step-by-step explanation:
Bilirubin is a brown pigment that is a byproduct of the catabolism of red blood cells and is excreted in feces by the large intestine. We distinguish between conjugated and unconjugated bilirubin. Conjugated bilirubin is also known as direct bilirubin, which is water-soluble and is the byproduct processed by the liver that can be directly excreted into the bile duct and eventually into the intestines. On the other hand, unconjugated bilirubin or indirect bilirubin, combines with albumin in the blood to be transported to the liver for processing. In conditions like obstructive jaundice, there is an increase in conjugated bilirubin due to bile duct obstruction. Therefore, another name for post-liver bilirubin is direct bilirubin, as it has already been processed by the liver.
