The pancreas is a gland organ in the digestive and endocrine system of human body. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as an exocrine gland, secreting pancreatic juice containing digestive enzymes that pass to the small intestine. These enzymes help in the further breakdown of the carbohydrates, protein, and fat in the chyme.
The pancreas is about 6 inches long and is shaped like a flat pear. The pancreas is located deep in the abdomen, sandwiched between the stomach and the spine. It lies partially behind the stomach.
Because the pancreas is a storage depot for digestive enzymes, injury to the pancreas is potentially very dangerous. A puncture of the pancreas generally requires prompt and experienced medical intervention.
