* D cells produce somatostatin; and. * F or D1 cells produce pancreatic polypeptide. These hormones are all polypeptides. Insulin is secreted only by the B cells whereas the other hormones are also secreted by the gastrointestinal mucosa and somatostatin is also found in the brain.
Alternate Answer: The pancreas produces digestive enzymes, but it also has Islets of Langerhans that sense the sugar level in the blood coming into the pancrease and produce insulin and the insulin gets into the blood before it goes to the liver.nsulin (and  glucagon) is secreted in the pancreas. Both of these hormones  control your blood sugar level. If it's too high, insulin is  released to put the sugar into the surrounding blood vessel cells,  and vice versa for glucagon.
