Homeostasis!
homeostasis
The inability to regulate blood glucose levels is referred to as diabetes mellitus.
insulin
high & low blood sugars, respectively
Regulation of blood glucose is handled by the body's production of insulin. Insulin moves the glucose that is produced during digestion out of the bloodstream and into cells.
Insulin and Glucagon
pancrease
regulate the amount of insilun and add sugar to the blood if it is low.
The pancreas secretes insulin that regulates glucose (blood sugar) metabolism.
There are two hormones that regulate blood glucose levels. One is insulin. This horemone "carries" glucose into the cell. No glucose and the cell starves and the glucose levels get higher in the blood. The second hormone takes glucose out of liver storage and increases the glucose in the blood. These two are a feedback mechanism that keeps the levels in a normal range.
the body needs to retain blood glucose simply because without it we would all die
The liver
Fasting Plasma Glucose (FPG)
