MICROANATOMY

Detailed explanation-1: -Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood.

Detailed explanation-2: -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.

Detailed explanation-3: -Glucagon is a 29-amino acid peptide hormone predominantly secreted from the alpha cells of the pancreas.

Detailed explanation-4: -The pancreas produces digestive juices and insulin, as well as other hormones to do with digestion. The part which produces the digestive juices is called the exocrine pancreas. The part which produces hormones, including insulin, is called the endocrine pancreas.

Detailed explanation-5: -Since the pancreas has both endocrine and exocrine functions, it is therefore a mixed gland. Its endocrine secretions are the hormones insulin and glucagon.
