(6) ______________ helps your cells absorb the glucose in your blood, allowing it to be used as energy. A healthy pancreas releases a regular supply of insulin into your bloodstream. After you eat, your blood glucose levels rise and your pancreas responds by releasing more insulin to move the glucose into your cells. Insulin acts as a key, opening up the cell so it can accept the glucose. In a person with type 1 diabetes, the pancreas produces little or no insulin. Without insulin, blood glucose levels rise. Without insulin glucose cannot enter the cells and be used for energy, as a result, it remains in the bloodstream. As a person with type 1 diabetes, it is important to (7) ____________________healthy blood glucose levels. High blood glucose levels over a long period of time can lead to health complications.
