How is blood glucose controlled in homeostasis?

Blood glucose increases and gets too high, this is detected by beta cells in the Islet of Langerhans. Increase in insulin secretion, this speeds up the rate of glucose uptake by tissue cells. Glucose gets turned into glycogen in the liver. Blood glucose levels are reduced.
Blood glucose decreases and gets too low, this is detected by beta cells in the Islet of Langerhans. Increase in glucagon secretion. Glycogen gets turned into glucose in the liver, and it passes out of cells into blood. Blood glucose levels are increased.
Decreased Blood Glucose (Too low). Detected by alpha cells in Islets of Langerhans. Increased in glucagon secretion. Glycogen gets turned into glucose (in liver). Formation from other substances such as amino acids. Glucose passes out of cells into blood.
