part_of calculated total pancreatic islet beta cell weight calculated weight of islet beta cells in duodenal region of pancreas 2013-10-11T16:25:01Z A measurement, which has been normalized, adjusted or derived by a mathematical process or computation, of the weight (the heaviness or the force with which an object is drawn toward the earth by gravity) of the islet beta cells in the head region of the pancreas, the portion of the pancreas which lies closest to the duodenum, the first segment of the small intestine, and contains the major pancreatic duct. The pancreas is the elongated, racemose gland containing both endocrine and exocrine elements which secretes hormones such as insulin and glucagon internally and digestive enzymes externally. A pancreatic islet is a small encapsulated region of the pancreas containing endocrine (i.e., hormone-producing) cells. An islet beta cell is a membrane-enclosed protoplasmic mass constituting the smallest structural unit of an organism that is capable of independent functioning, which is found in a pancreatic islet and produces the hormones insulin and amylin.
