What is a Serious condition in which the body temperature is greatly elevated because of retention of body heat?
hyperthermia
What is the ability of the human body to maintain a constant body temperature?
The human body has the remarkable capacity for regulating its core temperature somewhere between 98°F and 100°F when the ambient temperature is between approximately 68°F and 130°F according to Guyton. This presumes a nude body and dry air. The external heat transfer mechanisms are radiation, conduction and convection and evaporation of perspiration. The process is far more than the passive operation of these heat transfer mechanisms, however. The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors. Under control of these mechanisms, sweating begins almost precisely at a skin temperature of 37°C and increases rapidly as the skin temperature rises above this value. The heat production of the body under these conditions remains almost constant as the skin temperature rises. If the skin temperature drops below 37°C a variety of responses are initiated to conserve the heat in the body and to increase heat production. These include * Vasoconstriction to decrease the flow of heat to the skin. * Cessation of sweating. * Shivering to increase heat production in the muscles. * Secretion of norepinephrine, epinephrine, and thyroxine to increase heat production * In lower animals, the erection of the hairs and fur to increase insulation.
How does your body lose heat through urination and defecation?
Heat loss through urination and defecation occurs due to the high water content in urine and feces. When urine leaves the body, it takes away some heat with it. Similarly, when feces are eliminated, they also carry away a small amount of heat. However, the overall amount of heat lost through these processes is relatively small compared to other mechanisms such as evaporative cooling through sweating.
What type of heat is body heat?
Body heat is the heat that your body has and sweat to cool your body down .
Do cold blooded creatures give off body heat?
reptiles blood is not really cold, it just means that when reptiles are in the shade they cool down and when they go into the sun they can warm up. the difference between the warm blooded is that warm blooded does not cool and heat as much as the cold blooded. reptiles need it so they can withstand the temperature.
What is heat retention?
Heat retention is referred to as the energy transferred resulting in a difference in temperature. This allows for heat to be magnified in a specific area.
What is a Serious condition in which the body temperature is greatly elevated because of retention of body heat?
hyperthermia
What are the mechanisms of heat gain in the human body?
high metabolic rates, shivering,
Which mechanisms help the body conserve heat?
Shivering and vasoconstriction... B for plato users (:
Which rock retains heat best?
The denser the rock, the better the heat retention. Therefore a basalt would have better heat retention than a limestone, on a volume basis The best minerals for heat retention are a group of aluminosilicates called zeolites, and include minerals such as chabazite and analcime.
What is the cause of primary hypothermia?
Primary hypothermia occurs when the body's heat-balancing mechanisms are working properly but are subjected to extreme cold.

What is the retention of heat from the sunlight called?
It is called solar gain.
Who contributed to heat retention?
1 person who did is Benjamin Thompson
Where is the thermostat of vertebrates located?
The hypothalamus gland is the body's thermostat. It also links the nervous system to the endocrine system via the pituitary gland. It controls body heat and temperature, hunger, thirst and sleep among other functions. The hypothalamus is also responsible for certain types of metabolism.
What will insulate better a foam or paper?
foam has better heat retention
