GENERAL HISTOLOGY

Detailed explanation-1: -The most important hormone that the pancreas produces is insulin. Insulin is released by the ‘beta cells’ in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues.

Detailed explanation-2: -The main hormones secreted by the endocrine gland in the pancreas are insulin and glucagon, which regulate the level of glucose in the blood, and somatostatin, which prevents the release of insulin and glucagon.

Detailed explanation-3: -Free amino acids, including alanine and glutamine, are released into the blood and serve as potent glucagon secretagogues. This results in elevatation of blood glucose levels, which then triggers insulin secretion.

Detailed explanation-4: -Secretin and cholecystokinin (CCK) are the two hormones that stimulate pancreatic secretion. Secretin stimulates the secretion of water and bicarbonates. CCK stimulates the secretion of pancreatic enzymes.
