Pancreatic Amylase Secretion: The Role of the Pancreatic Duct & Duodenum

The correct answer is: thoracic duct.

Pancreatic amylase is synthesized by the pancreas and secreted into the pancreatic duct. The pancreatic duct joins the common bile duct to form the ampulla of Vater, which opens into the duodenum. Pancreatic amylase is released into the duodenum along with other pancreatic enzymes and bicarbonate ions.

The thoracic duct is a lymphatic vessel that drains lymph from the upper body. It does not transport pancreatic amylase to the small intestine.
