Detailed explanation-1: -Through its various hormones, particularly glucagon and insulin, the pancreas maintains blood glucose levels within a very narrow range of 4–6 mM. This preservation is accomplished by the opposing and balanced actions of glucagon and insulin, referred to as glucose homeostasis.

Detailed explanation-2: -Insulin is the main regulator of sugar in the bloodstream. High insulin levels drive sugar out of the bloodstream into muscle, fat and liver cells where it is stored for future use. Low insulin levels allow sugar and other fuels to be released back into the blood stream.

Detailed explanation-3: -Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal.
