What about the assistance of fever?

Last week I did not post a blog because my body was feverish and I did NOT feel up to writing at the computer.  When confronted by some organisms, macrophages produce a substance called interleukin-1 , which triggers fever.  Once releases by the macrophage, the interleukin-1 travels though 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.  Nerve impulses from the hypothalamus then spark the body’s heat conserving mechanisms, blood vessels in the skin constrict, preventing heat loss; muscles contract, causing shivering.  We cover up with sweaters and blankets until the body temperature reaches its new set point.

Amazing isn’t it?
