Final answer:
The dorsal pancreatic bud develops into the exocrine pancreas, consisting of acinar cells and pancreatic ducts which secrete digestive enzymes into the small intestine.
Step-by-step explanation:
The dorsal pancreatic bud becomes the majority of the exocrine pancreas, including the pancreatic ducts and the acinar cells which produce digestive enzymes. The ventral bud, alongside with the dorsal, forms the complete pancreas.
The exocrine part of the pancreas arises as clusters called acini, which are the terminal ends of pancreatic ducts. Acinar cells within these acini secrete enzyme-rich pancreatic juice into merging ducts, eventually draining into the main pancreatic duct. This duct joins the common bile duct to enter the duodenum at the hepatopancreatic ampulla, controlled by the hepatopancreatic sphincter, which regulates the flow of bile and pancreatic juice into the small intestine.
