Document Summary
Secretes glucagon to increase the glucose from non-carbohydrate sources (gluconeogenesis). It can also break down the glycogen to provide the necessary glucose levels. Insulin decreases the blood serum glucose level because it causes the transport of glucose into the cells and also storing it in the liver. The pancreas is a dual gland, meaning it has endocrine (secretes into the blood) and exocrine (secretes into small ducts and then the blood) functions. Mellitus (iddm: more frequent in children/teens, results from insulin deficiency (from beta cell destruction, an autoimmune process, more severe form/requires replacement therapy. Dm: due to effectiveness of insulin or relative deficit, production, high insulin resistance, high glucose production by the liver, older adults- pt"s often overweight. Increasing incidence in teens and young adults as a component of metabolic syndrome: milder form of disease/ can be controlled by diet or stimulation of beta cells to increase insulin production.
