Final answer:
The main pancreatic duct is known as the duct of Wirsung, and it plays a key role in delivering pancreatic juice to the duodenum for digestion.
Step-by-step explanation:
The main pancreatic duct is called the duct of Wirsung. This duct is important for the transport of enzyme-rich pancreatic juice from the pancreas into the duodenum, the initial part of the small intestine. The pancreatic juice is critical for digestion as it contains enzymes like maltase that break down sugars.
The duct of Wirsung fuses with the common bile duct before entering the duodenum through the hepatopancreatic ampulla which opens at the major duodenal papilla. The flow of pancreatic juice and bile into the duodenum is regulated by the hepatopancreatic sphincter often referred to as the sphincter of Oddi.
