How Does the Body Keep Blood Glucose Levels in Check?
Glucose is the primary source of energy for the body. In fact, it is normally the only fuel used by the brain’s nerve cells, called neurons. Neurons can’t store glucose for back-up energy, so a constant supply must be available in the blood. However the supply must be kept in balance because too much sugar in the blood causes damage to cells throughout the body. Control of the amount of glucose in the blood depends on two hormones that are produced and secreted by the pancreas.
