Pancreas
The pancreas is an organ that in humans lies in the abdomen, stretching from behind the stomach to the left upper abdomen near the spleen. In adults, it is about long, , and salmon-coloured in appearance.

Anatomically, the pancreas is divided into a "head", "neck", "body", and "tail". The pancreas stretches from the inner curvature of the duodenum, where the head surrounds two blood vessels: the superior mesenteric artery, and vein. The longest part of the pancreas, the body, stretches across behind the stomach, and the tail of the pancreas ends adjacent to the spleen.

Two ducts, the main pancreatic duct and a smaller accessory pancreatic duct, run through the body of the pancreas, joining with the common bile duct near a small ballooning called the ampulla of Vater. Surrounded by a muscle, the sphincter of Oddi, this opens into the descending part of the duodenum.
where is the pancreas situated in the human body In the abdomen, behind the stomach what is its role? As a part of the digestive mechanism, it secretes pancreatic juice into the duodenum, and as an endocrine gland, it secretes insulin, glucagon somatostatin and pancreatic polypeptide, thereby maintaining blood sugar levels.
