Cells of the pancreas (an organ located in the abdomen that is part of the digestive system) determine the set point for blood glucose (blood sugar). After a meal, glucose levels are elevated and the pancreas detects the change and produces insulin. Insulin and glucose move into the bloodstream where they are transported to different areas of the body. The insulin allows glucose to move from the bloodstream into the muscles and liver where the glucose is stored or used as energy for cellular work.
