Question

Duct of Wirsung is a duct of
a. Liver
b. Pancreas
c. Gallbladder
d. Duodenum

Answer 1

Pancreatic duct is also called as Duct of Wirsung, it is the major pancreatic duct, in the pancreas, where it also has some accessory ducts called as Duct of Santorini, whereas Duct of Wirsung is a duct that joins the pancreas to common bile duct.

Complete answer:
There is a main duct in the pancreas which collects all juices from the branches of the pancreatic stream which exits at the main papilla of the pancreas.
Whereas there is another important duct in the pancreas which is said to be duct of Santorini that connects the major pancreatic duct usually in the duodenum
Sometimes this duct of Santorini stay remain open, usually it is closed at the fetal time itself, pancreas is present as 2 parts in the early development, where it is combined at the fetal stage during this time ,the ducts will usually close, but sometimes it may open so if there is any blockage also sometimes patients won’t feel any symptoms as the duct is open.
Ducts that present in the liver are bile ducts, their major function is to carry the bile or juices produced in the liver and gallbladder to the small intestine.
In the liver these bile ducts are again, intra hepatic and extra hepatic, whereas in the liver itself it is intra hepatic and itself joins with extra hepatic ducts.
All the ducts of liver, pancreas, gallbladder finally enters the duodenum to drain the digestive juices
So, from the above explanation the duct of Wirsung is a pancreatic duct.

Note: Duct of Wirsung in the pancreas is considered as a major duct because it also contains some accessory ducts, among them one of the ducts is the Santorini, so one should not confuse major ducts with accessory ducts.
