Final answer:
When sludge cannot be excreted from the liver, it can cause jaundice. This is due to a blockage in the bile ducts, preventing the excretion of conjugated bile pigments.
Step-by-step explanation:
When the sludge in the liver cannot be properly excreted, it can cause a condition called jaundice. Jaundice is characterized by a yellowish coloration of the skin and mucous membranes due to an accumulation of bilirubin, a waste product of red blood cell breakdown. This occurs when there is a blockage in the hepatic or common bile ducts, preventing the conjugated bile pigments from being excreted and causing them to regurgitate into the bloodstream and urine. This condition is known as choluric jaundice.
