Answer:
Glucagon is secreted
Explanation:
Glucagon is an hormone secreted by the alpha cells of the pancreatic islets. It is secreted when the blood glucose is low, when the blood glucose is high, glucagon is not secreted.
Glucagon affects the liver and some other cells but has more effect on the liver.
It allows for the release of glucose stored up in the liver cells into the blood stream to increase blood glucose.
