the stomach
The pancreas Functions as both….. (has both types of these cells)
endocrine and exocrine
Endocrine cells secrete of ______ and _______
insulin and glucagon
Exocrine cells secrete ____ _____ via ducts in the intestine

The pancreas has Pancreatic Islets, also known as
islets of Langerhans
The pancreas has Pancreatic Islets, also known as
islets of Langerhans
Pancreatic Islets have what 2 types of cells
Alpha and beta cells
what do alpha cells do in the pancreas?
synthesize glucagon
what do beta cells do in the pancreas?
produce insulin
What type of ‘glycemic’ hormone is Glucagon?
a hyperglycemic hormone
Glucagon the hyperglycemic hormone breaks down ______ into ______ in ap process known as_____

Insulin is the what type of ‘glycemic’ hormone?
hypoglycemic
Insulin lowers blood ____ ____
glucose levels
Insulin enhances membrane transport of glucose into ____ and _____ cells and therefore takes glucose _____ of the blood stream
muscle and fat
out
Insulin inhibits the breakdown of glycogen to…..
glucose
Insulin also accelerates uptake of amino acids by cells and increases….
protein synthesis
when detecting high blood sugar, Witch are responsible for the secretion of insulin in in the pancreas, alpha or beta cells?

insulin stimulates glycogens formation in what organ? where does that glycogen go?
