Pancreas

The pancreas is an organ capable of secreting hormones in both endocrine and exocrine fashion

Pancreatic Duct

 * It begins at the tail and joins the bile duct at the head, forming the Ampulla of Vater
 * The Ampulla of Vater enters the descending part of the duodenum at the major duodenal papilla
 * The accessory pancreatic duct enters the duodenum through the minor duodenal papilla

Islets of Langerhans
The Islets are a group of cells that create and store the hormones:-
 * Alpha cells - glucagon
 * Beta cells - insulin
 * Delta cells - somatostatin

Syntopy

 * The head of the pancreas lies next to the duodenum
 * From the lower part of the head is the uncinate process, which passes posteriorly to the superior mesenteric vessels
 * The neck is anterior to the superior mesenteric vessels
 * The portal vein behind the neck is formed by the superior mesenteric and splenic vein
 * The tail passes between the layers of the spleno-renal ligament
