Detailed explanation-1: -Insulin is a hormone produced in the pancreas by special cells, called beta cells. The pancreas is below and behind the stomach. Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy.

Detailed explanation-2: -Tucked away behind the stomach is an organ called the pancreas, which produces insulin. Insulin production is regulated based on blood sugar levels and other hormones in the body. In a healthy individual, insulin production and release is a tightly regulated process, allowing the body to balance its metabolic needs.

Detailed explanation-3: -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. ‘Alpha cells’ in the islets of Langerhans produce another important hormone, glucagon.

Detailed explanation-4: -The pancreas is the organ that produces the hormone insulin. It plays a major role in regulating blood glucose levels and diabetes. Type 1 diabetes occurs when the pancreas does not make enough or any insulin. Conversely, type 2 diabetes develops when the body cannot use insulin correctly.

Detailed explanation-5: -The endocrine cells of the pancreas Groups of endocrine cells are found throughout the pancreas. They are called islets of Langerhans because they are scattered like small islands (“islets”) and were discovered by the pathologist Paul Langerhans. These groups of cells produce insulin, glucagon and other hormones.
