. . . the process is called: HOMEOSTASIS
. . .and your point IS? . . . .
OK. Actually i know about regulation of temperature.
Still, when i ask what keeps the body at 98 degreees i am asking for the heat source.
. . . viz . . . I gotcha' point, John . . . browsed the posts quickly . . . . just a comment . . .don't visit this thread often . . .
Metabolism? So you think that produces near 100 degrees?
And if you go outside and it is 20 degrees you body says 98 degrees. Are you saying that metabolism keeps the body warm in 20 degree weather?
I read about metabolism, where does it say it produces 100 degree heat?
Nothing "produces" temperature. If it's 100 degrees out, then it takes zero energy to maintain something at 100 degrees. Things do, however, produce heat, and we generate between about 80 and 1600 watts depending on our activity level.
With enough insulation - yes.
It doesn't. It generates heat, not temperature.
Seriously. Bill, why compromise yourself? Are you saying there is no source of heat to keep an object at a steady 98 degrees?
Secondly, why am i being attacked (by certain members with free reign, no less) from the first post? I am asking a question...or am i missing something? Is this not what we do on a science forum? Even the "moderator" came in and took a shot. He is a fair moderator who is actually knowlegdable too.
did you piss a few people off or what?:shrug:
What is the source of the heat?
Metabolism.
i'm speechless.Metabolism?
John, let me take a shot at explaining the things you're asking about. In a effort to make it clear and direct, I'll skip over some of the deeper details - which aren't really needed to understand what you want to know.
First off, all the living cells in your body need food to survive so yes, they are all using metabolism. (There's quite a number of dead cells - as in the outer layer of skin, hair, finger- and toenails that were produced by living cells, but once produced quickly die.)
And it's entirely correct to think of metabolism as a "burning" process that produces heat. It's just a MUCH slower burning than we see in a flame. But the process is exactly the same; technically, it's called by the name "oxidation". And oxidation means just like it sounds - the combining of oxygen and a fuel. In what we normally think about as oxidation the fuel is something like wood or oil and happens rapidly and produces heat quickly. Metabolism is the exact same process except that the fuel is food and the process is VERY slow. It still produces heat, though, just at a much slower rate than what happens in burning/oxidizing that produces a flame.
Does that help?
