The pancreas has both exocrine and endocrine functions. It includes two types of exocrine cells. Secretory acinar cells produce trypsinogen, amylase, and lipase, which are vital for nutrient digestion and absorption. Ductal cells produce sodium bicarbonate which neutralizes the hydrochloric acid from the stomach. The pancreatic islets are responsible for endocrine functions and produce glucagon and insulin. 

This duct is also known as the duct of Wirsung. This duct drains the pancreatic fluid from the gland and carries it to the duodenum.  

This duct is also known as the duct of Santorini. It drains the remainder of the pancreas and leaves via the accessory papilla. 

The Ampulla of Vater is the spot where the pancreatic and bile ducts release their secretions into the intestines.

The sphincter of Oddi is the valve at the exit of the pancreatic duct and bile duct where they enter the duodenum. This valve is normally shut except after a meal when it opens to allow digestive fluids into the duodenum for digestion.
