Homeostasis is the process where your body releases Insulin and Glucagon
It’s a balancing game.
When there’s too much Glucose in the blood Insulin is released to store the Glucose as Glycogen
Inversely when there’s not enough Glucose, Glucagon is released to break Glycogen back down into Glucose
This is done by the pancreas, where theres alpha cells that release Glucagon and beta cells to release Insulin.
