How does your body generate the heat for body temperature?

The energy to generate heat has to come from somewhere. Is it the friction of the blood pumping through the veins and tissues in your body? Is there some kind of chemical heat generation at the cellular level? Where does the heat come from?

The heat comes from the energy in the food you eat. Your body burns calories to generate heat. You burn around 2000 calories a day just by existing.
