How body temperature is maintained?

Answer 1

body temperature can maintain by physiological method especially in mammals bcoz, they are homoiothrmic which rely mainly on metabolic heat to maintain their body temperature through negative feedback mechanism by triggering corrective mechanism example of physiological method are by :

1. increase in sweating
2. vasodilation & vasoconstriction
3. by the relaxation/contraction of pilo erector muscle
4. metabolic rate

Answer 2

The human body temperature is maintained by the constant burning of "fuel" in your cells.

Just like a car burns gasoline, the human body (chemically) burns carbohydrates (e.g. glucose) and lipides (fat). This occurs constantly, even in your sleep.

This "burning" is of course a chemical reaction that occurs in your cells. For this reaction a carbohydrate or fat has to react with oxygen, these will be converted to carbon dioxide (CO2), water and HEAT!!.

Because of that heat your body maintains its temperature.

Answer 3

The body temperature of humans is maintained close 37°C and heat is distributed throughout the body by blood. The hypothalamus of the brain has thermoreceptors which monitor temperature by sending messages to effectors.

When the person is too hot, the skin arterioles will dilate to cool the body. The sweat glands will also produce sweat and the evaporation of sweat has a cooling effect.

When the person is too cold, the skin arterioles constrict to retain body heat. Shivering can also generate heat.

Answer 4

This is called homeostatic thermoregulation, and is common in warm-blooded animals. Unlike cold-blooded animals, which cannot regulate their body temperatures, and have to find shade, sunlight, and other means, warm-blooded animals have internal structures that both sense body temperature and produce chemical/hormonal changes that can allow for the generation of heat as well as the dissipation of heat. For example, the human body has the hypothalamus in the midbrain, which controls the body's temperature regulation systems. It can trigger hormone changes to induce vasoconstriction (when we need to start warm and give off less heat through the skin) and vasodilation (when we need to cool down and dissipate more heat through the skin). The brain also induces shivering to generate chemical energy, which is converted to heat.

Answer 5

Homeostasis- proper maintenance of a relatively constant internal body fluids and bodily temperature

Answer 6

If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs.

Answer 7

shivering
