leva [86]

Answer:

The liver stores glucose to power the cells during periods of low blood sugar. Skipping meals and poor nutrition can lower blood sugar. By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon.
