WebInsulin helps glucose in your blood enter your muscle, fat and liver cells so they can use it for energy or store it for later use. When glucose enters your cells and the levels in your bloodstream decrease, it signals your pancreas to stop producing insulin. WebInsulin works in tandem with glucagon, another hormone produced by the pancreas. While insulin's role is to lower blood sugar levels if needed, glucagon's role is to raise blood sugar levels if they fall too low. Using this system, the body ensures that the blood glucose levels remain within set limits, which allows the body to function properly.
