Pancreas the culinary name of sweetbread. Pancreas The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity behind the stomach. The pancreas is a mixed gland, having both an endocrine and an exocrine function. As an endocrine gland, it secretes into the blood several important hormones, including insulin, glucagon, somatostatin, and pancreatic polypeptide. As an exocrine gland, it secretes pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates,
Insulin resistance the body is resistant to insulin action. Levels between 4.0 and 7.5 mg/min are not definitive, and suggest "impaired glucose tolerance," an early sign of insulin resistance. This basic technique may be enhanced significantly by the use of glucose tracers. Glucose may be labeled with either stable or radioactive atoms. Commonly used tracers are 3-H glucose (radioactive), 6,6 H-glucose (stable) and 1-C Glucose (stable). Prior to beginning the hyperinsulinemic period, a 3h tracer infusion enables one to determine the basal rate of glucose production. During the clamp, the plasma tracer concentrations enable the calculation of whole-body insulin-stimulated glucose metabolism, as
