  • Endocrine Pancreas 
    • Functional units are the islets of Langerhans, which are made up of:
      • Beta cells that produce insulin
        • Diabetes is caused by insufficient insulin, which causes increased blood glucose
          • Type 1 diabetes is caused by lack of insulin production 
          • Type 2 diabetes is caused by broken insulin receptors 
      • Alpha cells that produce glucagon
      • Delta cells produce somatostatin
        • Hormone that has a generalized inhibitory effect on digestive function and has been shown to suppress insulin and glucagon release.
        • Stops function of all other active hormones
