Explain the Pancreas

The pancreas is a gland that lies immediately below the stomach, surrounded by the loop of duodenum. The bulk of the pancreas is composed of pancreatic exocrine cells, whose ducts are arranged in clusters called acini (singular acinus).

The cells are filled with secretory granules containing the digestive enzymes. Embedded throughout the exocrine tissue are small clusters of cells called the Islets of Langerhans, which are the endocrine cells of the pancreas and secrete insulin, glucagon and several other hormones. Here we shall focus on the endocrine cells which secrete the hormones. Let us learn about the hormones secreted from the endocrine cells of pancreas.
