Question

where does insulin and glucagon originate and what factors stimulate their release into the blood stream?

Answer 1

Answer: The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells. Hope this helps
