Final answer:
Pancreatic juice is carried to the duodenum via the main pancreatic duct, which joins the common bile duct and enters the duodenum at the major duodenal papilla.
Step-by-step explanation:
The correct description of the function of the pancreatic ducts is that pancreatic juice travels to the duodenum via the main pancreatic duct. The main pancreatic duct, also known as the duct of Wirsung, fuses with the common bile duct before entering the duodenum at the major duodenal papilla. This is managed by the hepatopancreatic sphincter, which regulates the flow of bile and pancreatic juice from the ampulla into the duodenum.
Contrarily, the accessory pancreatic duct, or duct of Santorini, when present, is a development remnant that also empties into the duodenum, but usually at the minor duodenal papilla.
