The common bile duct and the pancreatic duct empty into the duodenum at a specific anatomical site known as the Ampulla of Vater. This structure is an important junction where bile from the liver and digestive enzymes from the pancreas converge to enter the small intestine, facilitating the digestion and absorption of nutrients.

The Ampulla of Vater is found within the descending part of the duodenum, marking a critical point of entry for bile and pancreatic secretions, which are essential for fat digestion. The coordinated release and regulation of these fluids into the duodenum help maintain digestive processes.

The other options listed, though they are parts of the small intestine, do not specifically serve as the outlet for the bile and pancreatic ducts. The duodenum itself is where the Ampulla of Vater is located, but it is distinct from the ampulla. The jejunum and ileum are sections of the small intestine further downstream, involved in nutrient absorption but not directly connected to the ducts in question.
