How do we maintain 98.6 degrees?

    Generally the human body regulates temperature through perspiration, conduction, convection, and radiation.  The body thermometer is the hypothalmus.  Through feedback from neurons, the body is able to regulate temperature.  When it is hot, we of course sweat and radiate heat.  When it is cold, the body constricts blood vessels to keep the warm core temperature.  If it is too cold, we start shivering to produce heat in muscles.  There is also a secretion of norepinephrine, epinephrine, and thyroxin to produce heat.

    Many mechanisms in the body work together in synchrony to maintain our internal bodily environment. Heat is generated through cellular metabolisms, which produces heat as a biproduct. At it’s simplest, cellular metabolism increases or decreases to maintain our core temperature. Alos, to cool down when we overheat, our body produces sweat. To warm up when we are getting colder, we do things like shiver, and our body sends blood away from the peripheries, and towards the core, to warm vital organs. The ability of the body to employ mulitple mechanisms to maintain a stable internal environment is called homeostasis.
