The pancreas lies obliquely in the upper abdomen with the main pancreatic duct in its center. From right to left the pancreas is divided into the head, body, and tail. Sometimes the portion between the head and body is called the pancreatic neck. The pancreatic head is folded inferiorly along the medial aspect of the second portion of the duodenum. The tip of the pancreatic head, which is curved and pointing to the left, is called the uncinate process. Anterior to the pancreatic head lie the gastric antrum and duodenal bulb, and posteriorly the inferior vena cava. The splenic vein runs transversely, posterior to the body of the pancreas. This vein joins the superior mesenteric vein behind the neck of the pancreas to form the portal vein. The junction of these two veins is called the splenoportal confluence. The pancreatic tail is located anterior to the left kidney, and its tip approaches the splenic hilum. Anterior to the pancreatic tail are the body of the stomach and the splenic flexure of the large intestine.
