The uncinate process is the part of the gland that bends backwards and underneath the head of the pancreas. Two very important blood vessels, the superior mesenteric artery and superior mesenteric vein, cross behind the neck of the pancreas and in front of the uncinate process. The pancreas is both an exocrine gland and endocrine gland and has two main functions digestion and blood sugar regulation.
