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.
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.
The honey bee, for example, does so by contracting antagonistic flight muscles without moving its wings (see insect thermoregulation). [ 18 ] [ 19 ] [ 20 ] This form of thermogenesis is, however, only efficient above a certain temperature threshold, and below about 9–14 °C (48–57 °F), the honey bee reverts to ectothermy.
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. [34] When the core temperature falls, the blood supply to the skin is reduced by intense vasoconstriction. [18]
Thermoregulation, or body temperature control, in animals, including humans. Subcategories. This category has the following 3 subcategories, out of 3 total. D.
Homeothermy is one of the 3 types of thermoregulation in warm-blooded animal species. Homeothermy's opposite is poikilothermy . A poikilotherm is an organism that does not maintain a fixed internal temperature but rather its internal temperature fluctuates based on its environment and physical behaviour.
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.
A similar example is given by the Senegalese sole (Solea senegalensis), which, when acclimated to temperatures of 26 °C, produced a significantly higher amount of taurine, glutamate, GABA and glycine compared to acclimation to 12 °C. This may mean that the aforementioned compounds aid in antioxidant defense, osmoregulatory processes, or ...
