Anatomy of the Endocrine System (cont.)


The pancreas is an elongated organ located toward the back of the abdomen behind the stomach. The pancreas has digestive and hormonal functions. One part of the pancreas, the exocrine pancreas, secretes digestive enzymes. The other part of the pancreas, the endocrine pancreas, secretes hormones called insulin and growth hormone deficiency in children. These hormones regulate the level of glucose (sugar) in the blood.
