Final answer:
The pancreas has ducts that ultimately open into the duodenum, and it functions as both an endocrine and exocrine gland, providing necessary enzymes for digestion.
Step-by-step explanation:
The duct of the pancreas ultimately opens into the duodenum. The pancreas is a glandular organ located in the abdomen behind the stomach. It has two major ducts, the main pancreatic duct and the accessory pancreatic duct, which both drain into the duodenum.
The gland whose duct ultimately opens into the duodenum is the pancreas. The pancreas is unique in that it functions as both an endocrine and exocrine gland. The exocrine part consists of acinar cells that secrete pancreatic juice which is rich in digestive enzymes. These enzymes are important for the digestion of food as they are funneled into the duodenum through the pancreatic ducts. The main pancreatic duct often merges with the common bile duct before entering the duodenum at the hepatopancreatic ampulla, whereas the accessory duct (duct of Santorini), if present, enters the duodenum independently.
