The tail of the pancreas, located anatomically left near the hilum of the spleen, is not simply an antomical distinction. The tail is the only part of the pancreas which contains Pancreatic Polypeptide (PP) cells, which are responsible for secreting pancreatic polypeptide to coordinate exocrine and isletenzyme release. PP cells are found in the tail's periphery. Beta cells (insulin secretory) and delta cells (somatostatin secretory) are found in the central part of the tail as with the rest of the pancreas.

The inferior surface of pancreas is narrow on the right but broader on the left, and is covered by peritoneum; it lies upon the duodenojejunal flexure and on some coils of the jejunum; its left extremity rests on the left colic flexure. ... The superior margin of pancreas is blunt and flat to the right; narrow and sharp to the left, near the tail. ... The anterior margin of pancreas separates the anterior from the inferior surface, and along this border the two layers of the transverse mesocolon diverge from one another; one passing upward over the anterior surface, the other backward over the inferior surface. ... The Inferior margin of pancreas separates the posterior from the inferior surface; the superior mesenteric vessels emerge under its right extremity. ...

The Tail (cauda pancreatis) is narrow; it extends to the left as far as the lower part of the gastric surface of the spleen, lying in the phrenicolienal ligament, and it is in contact with the left colic flexure.
As the pancreas extends to the left toward the spleen it crosses the upper part of the kidney, and is so moulded on to it that the top of the kidney forms an extension inward and backward of the upper surface of the pancreas and extends the bed in this direction.
—The arteries of the pancreas are derived from the lienal, and the pancreaticoduodenal branches of the hepatic and superior mesenteric.
The pancreas is divided into 4 regions: the head (which includes the uncinate process), the neck, the body, and the tail of the pancreas.
The tail of the pancreas lies in the left, upper part of the abdomen, under the lower rib cage and next to the spleen.
To the right of the body is the thin neck of the pancreas which connects the body to the head of the pancreas and which is located just in front of the major arteries and veins of the intestines--the portal vein, superior mesenteric vein, and superior mesenteric artery.
