2 hormones produced by pancreas
|
insulin (β cells in islets of langerhans) - glucagon (α cells in islets of langerhans)
|
|
|
gland that produces insulin (β cells in islets of langerhans)
|
pancreas
|
|
|
insulin (β cells in islets of langerhans) is stimulated by
|
↑blood sugar - ↑amino & fatty acids
|
|
|
insulin (β cells in islets of langerhans) is inhibited by
|
↓blood sugar + GHIH
|
|
|
insulin (β cells in islets of langerhans) targets
|
all body cells
|
|
|
effects of insulin (β cells in islets of langerhans)
|
↓blood sugar levels by enhancing membrane transport of glucose - inhibits breakdown of glycogen into glucose
|
|
|
gland that produces glucagon (α cells in islets of langerhans)
|
pancreas
|
|
|
glucagon (α cells in islets of langerhans) is stimulated by
|
↓blood sugar
|
|
|
glucagon (α cells in islets of langerhans) is inhibited by
|
↑blood sugar - somatostatin (GHIH)
|
|
|
glucagon (α cells in islets of langerhans) targets
|
liver
|
|
|
effects of glucagon (α cells in islets of langerhans)
|
causes release of glucose into blood from glycogen in the liver - promotes glucogenesis (production of glucose from non-carb. Sources)
