The hypothalamus in the brain

Heat is basically retained or released to the environment by respiration (breathing out heat), radiation (heat emits into the environment by the skin), snd other means (conduction of heat by heat conductors such as ice or water, etc. As far as how the body controls excess body temperatures, blood vessels, called capillaries, near the surface of the skin dilate and allow more blood to enter them, because they are close to the surface, they allow blood to radiate more heat to the environment. Internal temp is also controlled via the sweat glands. The sweat evaporates and creates additional cooling capabilities.
In cold weather, the reverse happens. in addition shivering adds body temperature by creating muscular action. Another primitive reaction occurs where the erector pili muscules contract, causing the ever popular goose bumps. When humans possessed more hair, the erector pili muscles would have made the hair stand-up. This would provide a natural insulation.

A variety of mechanisms in the body control body temperature with the first and foremost thing being the hypothalamus in the brain although the skin, liver and other organs all play their part.

Hypothalamus

Hypothalamus,the part of the brain that lies below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate bodily temperature, certain metabolic processes, and other autonomic activities.

Hypothalamus. It is in charge of regulation systems in the body, including temperature.

My first answer would be "metabolism," because when one's metabolism is too low, one's body temperature is usually subnormal (& conversely, when metabolism is higher than normal, one's body temperature tends to be higher, also). Or did you mean something more general? Shivering will increase the body's temperature, sweating decreases it...a lot of different things can influence it.

I would assume blood pressure and insulation via fatty tissue

Your metabolism on the one side and what your pores and sweating does on the other.
