The pancreatic duct is generally regarded as abnormally enlarged if being over 3 mm in the head and 2 mm in the body or tail on CT scan. [9] Pancreatic duct or parts of pancreatic duct can be demonstrated on ultrasound in 75 to 85% of people. [10] Pancreatic ductal carcinoma is a common form of pancreatic cancer.
The ductal pancreas network originates from the central pancreatic duct—this main duct with the bile duct opens into the duodenum. The ductal cells of the main pancreatic duct are bound by connective tissue and produce a columnar epithelium. [3] Interlobular ducts originate from the main pancreatic duct and connect the various pancreatic lobes.
The isthmus (also called the central pancreas) is the region of the gland that runs anterior to the superior mesenteric artery; by convention, it divides the right and left sides of the pancreas. [2] The ventral pancreatic bud forms the pancreatic head and uncinate process. The glands continue to develop but the duct systems anastomose.

The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells , and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin .
Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. [1] The duct portion may be branched (called compound) or unbranched (called simple). The glandular portion may be tubular or acinar, or may be a mix of the two (called tubuloacinar). If the glandular portion branches, then ...
The minor papilla drains the duct of Santorini, superior in position to the major papilla. In pancreatic divisum, in which the minor papilla drains the bulk of pancreatic secretions and major drains a minority of secretions (opposite of normal), a Santorinicele may develop leading to obstructed secretions/reflux resulting in pancreatitis.
Aqueous pancreatic secretions from pancreatic duct cells contain bicarbonate ions which are alkaline and help with the bile to neutralise the acidic chyme that is churned out by the stomach. The pancreas is also the main source of enzymes for the digestion of fats and proteins.
