Glucose is the primary sugar in your blood — your body's preferred fuel source. Every cell in your body, especially your brain and muscles, runs on glucose. It comes from the food you eat, particularly carbohydrates, and is regulated by a hormone called insulin, produced by your pancreas.

Blood urea nitrogen — BUN — is a measure of how much urea is circulating in your bloodstream. To understand it, you need to understand where urea comes from.

Every single cell in your body relies on water and electrolytes for its fundamental functions and energy production.
