The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Sometimes the pancreas fails to develop normally and there may be congenital defects associated with the uncinate process. The uncinate process may split and encircle the duodenum, which is known as an annular pancreas. [3] There is also a common condition called pancreas divisum where the dorsal and ventral pancreas do not fuse properly.
There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.
The pancreatic duct or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct) is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas , which aids in digestion .
Pancreas divisum is a congenital anomaly in the anatomy of the ducts of the pancreas in which a single pancreatic duct is not formed, but rather remains as two distinct dorsal and ventral ducts. Most individuals with pancreas divisum remain without symptoms or complications.

In 10% of people, the minor duodenal papilla is the prime duct for drainage of the pancreas, [1] although in others it may not be present at all. [2] Pain from the region will be referred to the epigastric region of the abdomen due to its associated dermatomes. [citation needed]
