         Insulin decreases blood sugar levels. When your blood sugar level rises, the Islets of Langerhans, a special group
         of cells in the pancreas secrete MORE insulin. Insulin increases glucose utilization by making cells more permeable
         to glucose, and blood sugar levels are returned to a normal range. Insulin promotes not only the entry of glucose
         into the cells, but also facilitates its oxidation within the cells.
