Detailed explanation-1: -Insulin has an effect on a number of cells, including muscle, red blood, and fat. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range.
Detailed explanation-2: -Insulin helps blood sugar enter the body’s cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too.
Detailed explanation-3: -Insulin causes glucose to deposited in the liver as glycogen; then, during the next few hours, when blood glucose concentration falls, the liver releases glucose back into the blood, decreasing fluctuations. Clinical significance: During severe liver disease, it is impossible to maintain blood glucose concentration.
