Question

The given diagram shows the duct systems of liver, gall bladder and pancreas in which few structures are marked as $\mathrm{1.2.3}$ and $4$. On the basis of this figure answer the questions.

Which two ducts are responsible for the formation of a duct that carry bile from the gall bladder and conduct it into the first section of the small intestine?

• A. 1 and 2
• B. 2 and 3
• C. 3 and 4
• D. 4 and 1

Answer 1

Answer: (D)

Ducts [marked as 1(duct from gall bladder) and 4 ( duct from liver)] are responsible for the formation of common bile duct (marked as 2)].The common bile duct is a small, tube-like structure formed where the common hepatic duct (duct from liver) and the cystic duct (duct from gall bladder) join. Its function is to carry bile from the gallbladder and conduct it into the upper part of the small intestine (the duodenum). The common bile duct is part of the biliary system. Bile, a yellow-brown fluid which helps break down fats in food, is produced by the liver. It is stored and concentrated in the gallbladder until it is needed to help digest food.
