When confronted by some organisms, macrophages produce a substance called interleukin-1, which triggers fever. Once released by the macrophage, the interleukin-1 travels through the bloodstream to the tiny portion of the brain that controls body temperature — a small cluster of neurons deep within the hypothalamus.
The innate intelligence of the body through this chemical prompts the temperature regulator to set a new body temperature.
Amazing isn’t it?
