The Pancreas
The pancreas functions as a gland in the endocrine system and as an organ in the digestive system. It is a long (6-7 inches), thinner (1-2 inches) organ that is rounded (the head) on one end and slightly pointed (the tail) on the other. It is located diagonally behind the stomach and connects directly to the duodenum (small intestines), the gallbladder, and the liver. The pancreas consists of exocrine glands that secrete enzymes for digestion through the pancreatic duct, which runs through the center of the organ. The enzymes produced are lipase for fat; amylase for starches; and peptidase for proteins. Surrounding the ducts are grape like structures containing three groups of cells for endocrine functions. The three groups of islet or island cells are alpha, beta(70%), and delta(5%). These cells mainly produce the hormones glucagon (alpha) and insulin (beta) to be secreted into the blood stream. Insulin lowers blood sugar levels while glucagon slowly increases blood sugar if it falls too low. When the beta cells do not function properly diabetes can occur.
