What is glucose homeostasis in a human?

Homeostasis describes the maintenance of the body’s internal environment. Glucose homeostasis is specifically referring to the control of the levels of sugar in the blood.
The pancreas is an organ, which releases two important hormones. When it detects that blood sugar levels are too high, it releases ‘insulin’ to decrease the level. However, if it detects that there is too little glucose in the blood, the pancreas releases a hormone called ‘glucagon’, which works to increase blood glucose back to a normal value.
