  2. Cold and heat adaptations in humans - Wikipedia

    en.wikipedia.org/wiki/Cold_and_heat_adaptations...

    The human body always works to remain in homeostasis. One form of homeostasis is thermoregulation. Body temperature varies in every individual, but the average internal temperature is 37.0 °C (98.6 °F). [1] Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate.

  3. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes. Other species have various degrees of thermoregulation.

  4. Endotherm - Wikipedia

    en.wikipedia.org/wiki/Endotherm

    The resting human body generates about two-thirds of its heat through metabolism in internal organs in the thorax and abdomen, as well as in the brain. The brain generates about 16% of the total heat produced by the body. [8] Heat loss is a major threat to smaller creatures, as they have a larger ratio of surface area to volume.

  5. Homeothermy - Wikipedia

    en.wikipedia.org/wiki/Homeothermy

    Some homeotherms may maintain constant body temperatures through behavioral mechanisms alone, i.e., behavioral thermoregulation. Many reptiles use this strategy. For example, desert lizards are remarkable in that they maintain near-constant activity temperatures that are often within a degree or two of their lethal critical temperatures.

  6. Insect thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Insect_thermoregulation

    The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...

    Tigers in the wild typically have a lifespan of 10-15 years, according to the Smithsonian's National Zoo & Conservation Biology Institute. Tigers cared for by humans can live upwards of 20 years.

  8. Thermal neutral zone - Wikipedia

    en.wikipedia.org/wiki/Thermal_neutral_zone

    The human outer or peripheral shell (skin, subcutaneous fat etc.) acts as an adjustable insulator/radiator with the main mechanism of adjustment being blood flow to this compartment. If the surroundings are warm then heat loss is less, so the body directs more blood to the periphery to maintain the gradient for energy flow.
