Answer :
The accessory duct, or duct of Santorini, allows pancreatic juice to travel from the pancreas directly into the duodenum. It is a lesser-known duct that serves as a secondary pathway for the enzyme-rich and bicarbonate-laden pancreatic juice, especially important if the main pancreatic duct is blocked.
The pancreas is an important accessory digestive organ that secretes pancreatic juice, a substance crucial for proper digestion in the small intestine. The pancreas has a network of ducts, one of which is the smaller accessory duct, also known as the duct of Santorini. This duct allows pancreatic juice, which contains digestive enzymes like pancreatic amylase and bicarbonate, to travel directly from the pancreas into the duodenum.
Although not present in all individuals, the accessory duct is a developmental remnant and serves as an additional pathway for pancreatic juices, especially when the main duct is blocked or impaired.
