Final answer:
Posthepatic jaundice occurs as a result of biliary system blockage, preventing bile from entering the duodenum. This leads to an increase in conjugated bilirubin in the blood.

Jaundice that occurs as a result of biliary system blockage, which prevents bile from entering the duodenum, is known as Posthepatic jaundice. In this type of jaundice, there is an obstruction in the flow of bile in the bile ducts, leading to an increase in conjugated bilirubin in the blood. This can happen due to factors such as gallstones blocking the bile duct.
