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.
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. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2]
The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [2] Hyperthermia requires an elevation from the temperature that would otherwise be expected. Such elevations range from mild to extreme; body temperatures above 40 °C (104 °F) can be life-threatening.
Excess or reduced body weight is regarded as an indicator of determining a person's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight. Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on ...
Blood accounts for 7% of the human body weight, [9] [10] with an average density around 1060 kg/m 3, very close to pure water's density of 1000 kg/m 3. [11] The average adult has a blood volume of roughly 5 litres (11 US pt) or 1.3 gallons, [ 10 ] which is composed of plasma and formed elements .
Average daily variation in human body temperature. Many physical processes are related to temperature; some of them are given below: the physical properties of materials including the phase (solid, liquid, gaseous or plasma), density, solubility, vapor pressure, electrical conductivity, hardness, wear resistance, thermal conductivity, corrosion resistance, strength
The temperature of the testes is maintained at 34.4 °C, a little below body temperature, as temperatures above 36.7 °C impede spermatogenesis. [ 1 ] [ 5 ] There are a number of mechanisms to maintain the testes at the optimum temperature.
a natural spring with water temperature above human body temperature (normally about 37 °C ... giving the average spring in the complex an output of more than 325 ...
