Final answer:
The main pancreatic duct joins with the common bile duct and drains into the duodenum through the major duodenal papilla.
Step-by-step explanation:
The main pancreatic duct is the duct through which pancreatic juice drains from the pancreas. It merges with the common bile duct and enters the duodenum via the major duodenal papilla, a point of opening in the duodenum. This allows the pancreatic juice and bile to flow into the small intestine.
