Anatomy of the Pancreas & Duodenum
The pancreas has three main sections:
- Head: area of pancreas to right of left border of superior mesenteric vein.
- Body: area of pancreas between left border of superior mesenteric vein and left border of aorta.
- Tail: area of pancreas between left border of aorta and hilum of spleen.
The most common site of primaries is the head of the pancreas. The pancreas has two functional components: endocrine, to produce insulin and other hormones, and exocrine, to produce pancreatic juices for digestion. The pancreas is in direct contact with the stomach, duodenum, spleen, and major vessels of the abdomen.
