PANCREAS . Insulin is a polypeptide hormone that lowers blood glucose levels and increases storage of glycogen in the liver . Glucagon is a steroid hormone that raises the blood glucose level and stimulates the breakdown of glycogen in the liver . The pancreas is underneath the stomach, settled into the bottom curve of the stomach and attached to the entrance of the small intestine. . If the pancreas isn’t working a person can get Diabetes Mellitus or Diabetes insipidus PANCREAS . Insulin is secreted in small amounts throughout the day to control glucose level and in a larger amount while people are eating. It turns glucose from the food we eat into energy by transferring the glucose from our blood to our cells. . Glucagon is a counterbalance to insulin. It converts glycogen to blood sugar. Which takes action when you fast or take in too little sugar.
