  2. Adaptation to extrauterine life - Wikipedia

    en.wikipedia.org/wiki/Adaptation_to_extrauterine...

    Manifestations: When the newborn cries, there is a reversal of blood flow through the foramen ovale which causes the newborn to appear mildly cyanotic in the first few days of life. The heart rate of the newborn should be between 110 and 160 beats per minute and it is common for the heart rate to be irregular in the first few hours following birth.

  3. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    There are four avenues of heat loss: convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such ...

  4. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

  5. Convection (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Convection_(Heat_transfer)

    Convection-cooling is sometimes loosely assumed to be described by Newton's law of cooling. [6] Newton's law states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings while under the effects of a breeze. The constant of proportionality is the heat transfer coefficient. [7]

  6. Newton's law of cooling - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_cooling

    The statement of Newton's law used in the heat transfer literature puts into mathematics the idea that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings. For a temperature-independent heat transfer coefficient, the statement is:

  7. Thermal neutral zone - Wikipedia

    en.wikipedia.org/wiki/Thermal_neutral_zone

    Vasomotor responses allow control of the flow of blood between the periphery and the core to control heat loss from the surface of the body. Lastly, the organism can show insulation adjustments; a common example being "goosebumps" in humans where hair follicles are raised by pilomotor muscles, also shown in animals' pelage and plumage.

  9. Thermogenin - Wikipedia

    en.wikipedia.org/wiki/Thermogenin

    The lipase converts triacylglycerols into free fatty acids, which activate UCP1, overriding the inhibition caused by purine nucleotides (GDP and ADP). During the termination of thermogenesis, thermogenin is inactivated and residual fatty acids are disposed of through oxidation, allowing the cell to resume its normal energy-conserving state.
