Some cells in the pancreas secrete hormones which regulate the level of glucose in the blood. Most of the pancreas consists of tissues which are embedded in "nested" cells. These cells secrete the digestive enzymes into tubes which meet to form the main duct. This duct joins the "cystic" duct (which carries bile from the gallbladder) and forms a small chamber which opens into the duodenum.
