The islets of Langerhans are microorgans located in the pancreas.
<h3>The islets of Langerhans </h3>
The islets are formed by polygonal or rounded cells, arranged in cords, around which there is an abundant network of blood capillaries with fenestrated endothelial cells.
<h3>Types of islets of Langerhans</h3>
- Alpha (A) cells: secrete glucagon. In humans, these cells have regular-shaped granules containing a dense center surrounded by a clear region under the membrane.
- Beta (B) cells: secrete insulin and amylin. B cells have irregular granules with a center formed of irregular crystals of insulin complexed with zinc.
- Delta cells (D): synthesize somatostatin.
- PP (F) cells: contain a pancreatic polypeptide.
With this information, we can conclude that the islets of Langerhans are microorgans that constitute a large production of products for the maintenance of life.
