the hormone that helps release more glucose into the blood is called
Blood sugar regulation If the blood glucose level falls to dangerous levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels. They convert glycogen into glucose (this process is called glycogenolysis). The glucose is released into the bloodstream, increasing blood sugar. Hypoglycemia, the state of having low blood sugar, is treated by restoring the blood glucose level to normal by the ingestion or administration of dextrose or carbohydrate foods. It is often self-diagnosed and self-medicated orally by the ingestion of balanced meals. In more severe circumstances, it is treated by injection or infusion of glucagon.
Glycogen Approximately 4Â grams of glucose are present in the blood of humans at all times;[2] in fasted individuals, blood glucose is maintained constant at this level at the expense of glycogen stores in the liver and skeletal muscle.[2] Glycogen stores in skeletal muscle serve as a form of energy storage for the muscle itself;[2] however, the breakdown of muscle glycogen impedes muscle glucose uptake, thereby increasing the amount of blood glucose available for use in other tissues.[2] Liver glycogen stores serve as a store of glucose for use throughout the body, particularly the central nervous system.[2] The human brain consumes approximately 60% of blood glucose in fasted, sedentary individuals.[2]
