The main pancreatic duct is a vital structure in the pancreas, a gland located behind the stomach. This duct transports digestive enzymes produced by the pancreas to the small intestine, specifically the duodenum. It plays a crucial role in digestion by helping to break down fats, proteins, and carbohydrates. The main pancreatic duct runs the length of the pancreas and typically joins the common bile duct before emptying into the duodenum. This connection allows bile, produced by the liver, to mix with pancreatic juices, enhancing the digestive process. Proper functioning of the main pancreatic duct is essential for effective digestion.
