Why are our bodies warm?

Answer 1

Every cell in your body has an internal process in which hydrocarbon compounds are oxidized to produce energy. Most of that energy goes to some body function such as muscle contraction or nerve impulse creation, but every cell also gives off a small amount of waste energy as heat.

The temperature of the tissues, as provided by the metabolic process, is regulated by the body's capability to adjust blood circulation. Blood carries off excess heat and exhausts it through the lungs.

The answers you have gotten to this question give you a good reason to look things up for yourself instead of asking questions on Yahoo!Answers. All of the other answers were wrong, and some were just simpleminded.

If you want some good information, try an internet search on "Human Metabolism" or "regulation of body temperature."

Good luck!

Answer 2

we are called homeotherms...or wam blooded. We maintain a constant body temperature which is advantageous over poikeotherms (cold bloded animasl). THese are we can be active at all times of the day and live in cooler climates
Disadvantages is we need to eat more to produce the energy to maintain our temperatures (not that eating is much of a problem to some people!!!) Our cells are like little factories that produce enrgy (ATP) and warmth is also a by-product which we make use of it to.

Answer 3

We are warm because we get energy from the food we eat and use this to keep our blood warm. This we are mobile all the day and night, not like cold blooded animals, who are dormant until the sun warms them up. An in evolutionary terms this makes cold blooded animals easy prey.

Answer 4

We belong to the class of Mammalia and more so we are also homoeothermic...is the term right? It means we maintain a constant body temperature....sweating to keep cool while increasing our metabolism to keep warm in colder climate. Bradythermic is also used in this context. Find out the meanings.

Answer 5

Burning calories gives off heat and makes your body warm.

Answer 6

respiration is an intracellular process of oxidation of glucose in prescence of oxygen to form water, CO2 and energy in the form of ATP(Adenosine Tri Phosphate). ATP serves as fuel to the body metabolisms....each ATP, when consumed, gives out 18Kcal. of energy......40% of which is retrieved for bodily needs...and the rest 60% is given released to the atmosphere in the form of heat... this is what keeps our body warm.... the normal body temperature is 98.2 degrees Farenheit. or approx 36.5 degrees C.....
i hope this ans proves suficient.....

Answer 7

from memory, we as organism, have homeostatic mechnasim. the defination for homeostatsis is the maintenance of a relatively stable environment. Put it simply, in a biological context, the meaning of life is passing your genes to the next generation, however it must viable, i should say, superior, to the next generation. IN that sense you are living on....If that makes sense. and you can't give good genes to the next generation tuhs enabling survival of your species..if your internal system is out of whack not good....so we have to make sure our internal system are all okay-dokey...and we make that happen thru homeostatsis... heat is common and as organism, as part of of homeostatic mechanism, we maintain our body tempereatur..Our cells and enyzems (organic catlyst that make the chemical reaction our cells go through quicker so as to accomadate our life) denatures (meaning that the whole 3d shape of the enzyme is destroyed/broken) at temperature above 35 adn if we are below the optimum temperature, which is thirty five or sometihng like that, our enzymes are inactive......Homeostatic mechanism control the heat we have in our body....Heat is released as a by product in aerobic cellular resperation and we have in built mechanism and adaptions that control the temperature/heat such as flushing( i think its decreasing/increasing the concentration gradient between the skin and the outside enviroment thus dissapting(releasing) the heat), vasoconstriction (teh constriction , making it smaller,of blood vessels), vasodilation (the dilation or bigger vessels carrying blood which carries heat, don't ask me how) and marine animals such as fish have somekind of an adapation, i can't recall of teh top of my head, but it basically results in less heat being lost to teh out environment by transefering heat across the capillaries/vessels that goes to the heart....

Basically, heat is an important thing becuase it kind of kick start our enyzems which undergoes chemical reactions, such as aerobic cellular respiration etc, its like teh motor for our metabolism (the sum of all the chemical reaction that a cell goes through). We have physiological,behaviroul and physical/skeletal adaptions that make sure we are at an optimum temperature by either employing any of the various strategies/adaptions that all organism (except maybe plants) have....

Hope that helps you. If you are studying biology at a senior (year 11/year 12 VCE or SPM) you should find the ansewr in your text book...

Answer 8

Mine isn't that warm. Especially my feet. I get cold fast. But, our skin fat and muscles trap heat or are supposed to. Also your blood pressure and blood volume efect your temperature. Anemics and people with low blood pressure feel colder.

Answer 9

We regulate our temperatures by making heat or by cooling mechanisms to keep our body temperature stable. We make heat by "burning" glucose during aerobic respiration.

Answer 10

to keep other bodies warm!!
