<span>Insulin is normally secreted by the beta cells of the pancreas while glucagon by the alpha cells. The </span><span>amount of insulin secreted into the blood increases as the blood glucose rises. In the same way, as the blood glucose falls, the amount of insulin secreted by the pancreas goes down.</span>
