Explanation:
Detailed explanation-1: -Although it is primarily an exocrine gland, secreting a variety of digestive enzymes, the pancreas has an endocrine function. Its pancreatic islets-clusters of cells formerly known as the islets of Langerhans-secrete the hormones glucagon, insulin, somatostatin, and pancreatic polypeptide (PP).
