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 ...
Cold and heat adaptations in humans are a part of the broad adaptability of Homo sapiens. Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research ...
t. e. 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.
Behavioral thermoregulation takes precedence over physiological thermoregulation since necessary changes can be affected more quickly and physiological thermoregulation is limited in its capacity to respond to extreme temperatures. [33] When the core temperature falls, the blood supply to the skin is reduced by intense vasoconstriction. [17]
The range for normal human body temperatures, taken orally, is 36.8 ± 0.5 °C (98.2 ± 0.9 °F).[12] This means that any oral temperature between 36.3 and 37.3 °C (97.3 and 99.1 °F) is likely to be normal. [13] The normal human body temperature is often stated as 36.5–37.5 °C (97.7–99.5 °F). [8][9]In adults a review of the literature ...
Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by humans, animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort. They may also have additional functions of ridding animals of ...
Eccrine sweat glands (/ ˈɛkrən, - ˌkraɪn, - ˌkriːn /; from Greek ek (s) +krinein 'out (wards)/external+ secrete ') [ 3 ] are the major sweat glands of the human body. [ 4 ] Eccrine sweat glands are found in virtually all skin, with the highest density in the palms of the hands, and soles of the feet, and on the head, but much less on the ...
Eurytherm. A eurytherm is an organism, often an endotherm, that can function at a wide range of ambient temperatures. [ 1 ] To be considered a eurytherm, all stages of an organism's life cycle must be considered, including juvenile and larval stages. [ 2 ] These wide ranges of tolerable temperatures are directly derived from the tolerance of a ...
