Input (English): The lower and left lateral portions of this organ form the uncinate process, and many of its products empty through the duct of Wirsung. It is primarily composed of acinar cells, while other portions of it have recently been discovered to produce ghrelin in epsilon cells, along with somatostatin in delta cells. Its exocrine portions produce enterokinase, its namesake lipase, and trypsin, which are secreted into the duodenum. For 10 points, name this organ whose alpha and beta cells of the islets of Langerhans produce glucagon and insulin.
