Structure of Pancreas:

 It is a composite (mixed) gland which functions as both exocrine and endocrine gland.

 About 99% of pancreatic cells are arranged in clusters called acini (exocrine gland). These cells produce digestive enzymes which flow into gastrointestinal tract through a duct.

 Scattered among exocrine acini are tiny groups of endocrine tissue called islets of Langerhans.

 Two main types of cells in islets of Langerhans are α–cells and β–cells.

 The α–cells secrete a hormone called glucagon whereas β–cells secrete insulin.
