A long, irregularly shaped gland in vertebrate animals that is located behind the stomach and is part of the digestive system. It secretes hormones (insulin, glucagon, and somatostatin) into the bloodstream and digestive enzymes into the small intestine or gut. The pancreas also secretes sodium bicarbonate, which protects the lining of the intestine by neutralizing acids from the stomach.
A gland behind the stomach that functions in both the endocrine system and the digestive system. Its endocrine function involves the secretion into the bloodstream of insulin, which regulates the level of sugars in the blood. As part of the digestive system, the pancreas secretes into the small intestine a fluid containing enzymes that is used in the digestion of all foods.
