body heat?

Question

why our body makes heat?
and what part makes the most heat?
and how does the body changes heat when you have a fever?

Answer 1

Whenever one form of energy is changed into another, a byproduct is heat energy. Heat is a natural product of cellular respiration (the process that changes the chemical energy stored in food into the energy needed for cell function.

The cells that release the greatest amount of heat are muscle cells.

NOTE: The chemical reactions of life are too slow to sustain life. Our cells make other chemicals, called enzymes and enzymes speed up life's chemical processes. Without enzymes, there is no life.

Enzymes are inhibited in their function by temperatures that are higher (or lower as in hypothermia) than one's normal body temperature (note: the enzymes also work better when body temperature is slightly greater than normal, thus you "warm-up" before you exercise or compete). As a result, when you have a fever the enzymes are no longer effective and your cells cannot release the energy needed to function. You can tell that is happening because, depending on the intensity of the fever, you don't feel like doing anything as you are literally unable to function properly.

Answer 2

Our body makes heat b'coz
it is ability of an organism to keep its body temperature within certain boundaries, even when temperature surrounding is very different.

what part makes the most heat =?

Temperature is regulated in the hypothalamus, in response to PGE2. PGE2 release, in turn, comes from a trigger, a pyrogen.
The hypothalamus generates a response back to the rest of the body, making it increase the temperature set-point.

A pyrogen is a substance that induces fever. These can be either internal (endogenous) or external (exogenous). The bacterial substance lipopolysaccharide (LPS) is an example of an exogenous pyrogen

Answer 3

our body makes heat to balance with the sorrounding...our head cause when we are angry...temper goes out...and your head makes a smoke.heheheheh
