Topics | Endocrine System | What is the function of islets in the pancreas? Islets are groups of cells located in the pancreas that make hormones that help the body break down and use food. For example, alpha cells make glucagon and beta cells make insulin. They are also called islets of Langerhans.
The hormones secreted by the endocrine pancreas regulate metabolic functions throughout the body, in the digestive tract, or in the islets themselves. The islets of Langerhans contain three major cell types, alpha, beta and delta cells, that secrete glucagon, insulin and somatostatin, respectively.
