  2. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.

  3. Cold and heat adaptations in humans - Wikipedia

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

    Humans adapted to heat early on. In Africa, the climate selected for traits that helped them stay cool. Also, humans had physiological mechanisms that reduced the rate of metabolism and that modified the sensitivity of sweat glands to provide an adequate amount for cooldown without the individual becoming dehydrated. [17] [20]

  4. Thermal comfort - Wikipedia

    en.wikipedia.org/wiki/Thermal_comfort

    A thermal image of human. Thermal comfort is the condition of mind that expresses subjective satisfaction with the thermal environment. [1] The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate.

  5. Thermal energy - Wikipedia

    en.wikipedia.org/wiki/Thermal_energy

    Internal energy: The energy contained within a body of matter or radiation, excluding the potential energy of the whole system, and excluding the kinetic energy of the system moving as a whole. Heat : Energy in transfer between a system and its surroundings by mechanisms other than thermodynamic work and transfer of matter.

  6. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    As in other mammals, thermoregulation is an important aspect of human homeostasis. Most body heat is generated in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [15] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.

  7. Thermogenesis - Wikipedia

    en.wikipedia.org/wiki/Thermogenesis

    Thermogenesis is the process of heat production in organisms.It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily (Sauromatum venosum), and the giant water lilies of the genus Victoria.

  8. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    Body heat is generated by metabolism. [5] This relates to the chemical reaction in cells that break down glucose into water and carbon dioxide, thereby producing adenosine triphosphate (ATP), a high-energy compound used to power other cellular processes.

  9. Earth's internal heat budget - Wikipedia

    en.wikipedia.org/wiki/Earth's_internal_heat_budget

    The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) [1] and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth. [2]
