The Pancreas (Human Anatomy): Picture, Definition, Function, Location in the Body, and More
The pancreas is about 6 inches long and sits across the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic duct. The narrow end of the pancreas, called the tail, extends to the left side of the body.

Pancreas Conditions
- Diabetes, type 1: The body’s immune system attacks and destroys the pancreas’ insulin-producing cells. Lifelong insulin injections are required to control blood sugar.
- Diabetes, type 2: The pancreas loses the ability to appropriately produce and release insulin. The body also becomes resistant to insulin, and blood sugar rises.
- Cystic fibrosis: A genetic disorder that affects multiple body systems, usually including the lungs and the pancreas. Digestive problems and diabetes often result.
- Pancreatic cancer: The pancreas has many different types of cells, each of which can give rise to a different type of tumor. The most common type arises from the cells that line the pancreatic duct. Because there are usually few or no early symptoms, pancreatic cancer is often advanced by the time it’s discovered.
- Pancreatitis: The pancreas becomes inflamed and damaged by its own digestive chemicals. Swelling and death of tissue of the pancreas can result. Although alcohol or gallstones can contribute, the cause of most pancreatitis is unknown.
- Pancreatic pseudocyst: After a bout of pancreatitis, a fluid-filled cavity called a pseudocyst can form. Pseudocysts may resolve spontaneously, or they may need surgical drainage.
- Islet cell tumor: The hormone-producing cells of the pancreas multiply abnormally, creating a benign or cancerous tumor. These tumors produce excess amounts of hormones and then release them into the blood. Gastrinomas, glucagonomas, and insulinomas are examples of islet cell tumors.
- Enlarged pancreas: An enlarged pancreas may mean nothing. You may simply have a pancreas that is larger than normal. Or, it can be because of an anatomic abnormality. But other causes of an enlarged pancreas may exist and require treatment.
