Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. This process is one aspect of homeostasis: a dynamic state of stability between an animal's internal environment and its external environment (the study of such processes in zoology has been called ecophysiology or physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. This occurs when the body is exposed to constant temperatures of approximately 55° C, any prolonged exposure (longer than a few hours) at this temperature and up to around 70° C death is almost inevitable. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia.
Whereas an organism that thermoregulates is one that keeps its core body temperature within certain limits, a thermoconformer is subject to changes in body temperature according to changes in the temperature outside of its body. It was not until the introduction of thermometersthat any exact data on the temperature of animals could be obtained. It was then found that local differences were present, since heat production and heat loss vary considerably in different parts of the body, although the circulation of the blood tends to bring about a mean temperature of the internal parts. Hence it is important to identify the parts of the body that most closely reflect the temperature of the internal organs. Also, for such results to be comparable, the measurements must be conducted under comparable conditions. The rectum has traditionally been considered to reflect most accurately the temperature of internal parts, or in some cases of sex or species, the vagina, uterus or bladder.
Occasionally the temperature of the urine as it leaves the urethra may be of use. More often the temperature is taken in the mouth, axilla, ear or groin.
What else can I help you with?
What is insensible heat?
Also Latent Heat Loss. The heat that is lost through the continuous, unnoticed water loss that occurs with vaporization accounting for 10% of basal heat production. Evaporation accounts for the greatest heat loss when body head increases.. Does not result in temperature increase of surrounding air.
What are the problem caused by friction?
The problem caused by the Friction * The heat is produced. * efficiency of a engine is decreased. * The mechieneries will get old quickly. * Loss of energy in the form of heat.
What mechanisms of heat loss are contributing to joels feelings of coldness?
Possible mechanisms of heat loss contributing to Joel's feelings of coldness could include conduction (loss of heat to a cooler surface by direct contact), convection (movement of air carrying away body heat), radiation (heat loss to cooler surrounding objects), and evaporation (loss of heat through sweating). Inadequate clothing and low ambient temperature can also exacerbate heat loss.
A thermos bottle has a shiny interior What type of heat transfer does it prevent?
It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.
What is the primary mode of heat loss?
The primary mode of heat loss in humans is through radiation, where body heat is emitted in the form of infrared radiation. Other modes of heat loss include conduction, convection, and evaporation.
Can the loss of antifreeze cause you to lose your heat?
Yes, low coolant can cause a loss of heat in the cabin.
What areas in a building cause you to lose heat?
Windows, doors, floors and ceiling will cause heat loss.
How much energy is loss at each pyramid level and why is it loss?
An average of 90 percent of energy is lost at each pyramid level through respiration, heat, and waste.
Washer or dryer cause shrinkage cause color loss?
color loss, washer, always was on cold for color fastness. shrinkage is dryer, you can avoid this by using low heat or no heat tumble dry
Did accretinary collisions during Earth's formation cause heat loss?
Accretionary collisions during Earth's formation did cause some heat loss, as the kinetic energy from impacts was converted into heat. However, the heat loss from these collisions was likely not the primary contributor to the overall heating of the early Earth, as other processes such as radioactive decay and gravitational compression played larger roles in generating heat.
Explain the factors that account for the loss of energy in the transfer from mouse to cat?
The mouse use some energy is used in respiration(loss as heat) and the others used as growth( which will then pass on to the cat)
Heat exhaustion is cause by what prectange of loss of water during exercise?
Heat exhaustion is cause by what precent of loss of water duringexercise? Just losing 5% of water can cause heat exhaustion. I am taking a FLVS class, Lifestyle and Fitness Design and I just answered this right on a exam so I this is correct.
What causes car battery to die?
#1 cause Heat, #2 Heat, #3 Heat, #4 Sulfation usually caused by electrolyte loss because of heat.
What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
Is precipitation heat loss or heat gain?
heat loss
What is insensible heat?
Also Latent Heat Loss. The heat that is lost through the continuous, unnoticed water loss that occurs with vaporization accounting for 10% of basal heat production. Evaporation accounts for the greatest heat loss when body head increases.. Does not result in temperature increase of surrounding air.
What are the prducts of respiration?
The products of respiration (cellular respiration) are water (H2O), carbon dioxide (CO2) and heat.
