How Insulin Plays A Critical Role

One of the endocrine system's most important hormones is insulin, which plays a critical role in how your body uses food.

When you eat, your digestive system breaks food down into glucose, and the glucose circulates in your bloodstream (where it's often referred to as blood sugar). In response to the rise in glucose after a meal, the pancreas releases surges of insulin, whose job is to clean the glucose from the blood.

Insulin directs some of the glucose to the body's cells, which use it for energy. Some of the glucose is diverted to the liver, where it's converted into glycogen (stored glucose) for later use by the muscles. Insulin then helps turn any leftover glucose into fatty acids and stores them in fat cells, where they can be tapped later for fuel.
