Insulin is a hormone produced by the pancreas in healthy individuals. It causes cells in the liver, skeletal muscles, and fat tissue to absorb glucose from the blood. People with type 1 diabetes cannot produce their own insulin, and therefore require it from an external source, such as injection, in order to survive.
