What is human body temprature?
Human body temperature is the measurement of heat in the human body. The average person's body temperature is about 98.6 degrees Fahrenheit.
The ways in which a human can gain and lose heat?
A person can lose/gain heat in five ways: Conduction is the transfer of heat directly from one object to another. For example sitting on the cold leather seats of an unwarmed vehicle. Convection is the loss of heat through moving air or liquid. When it is cold we lose heat through the blowing wind Evaporation occurs when a liquid changes into a gas. Sweating is an example of evaporation. Radiation is heat sent outward into the air from your body and into nearby colder objects. It is also known as infrared energy. Respiraton is also when our body breathes in warm and humidified air and exhales carrying heat from the body.
How hot is your body?
Normal core temperature should be 98.6.
Where on the human body is the hair thick enough to retain heat?
your head
What organ of excretion is the largest in the body and gets rid of heat and urea?
The organ that excretes Urea compounds are the kidneys, BUT they do not excrete HEAT. No organ of the human body EXCRETES heat.
Which mechanisms help the body conserve heat?
Shivering and vasoconstriction... B for plato users (:
How do things gain heat?
Heat in a body is attained when there is rapid movement in the molecules of a body or when there is kinetic energy in the body.
What does it meat when body is cold outside even when you sweat?
The human body has a set temp of 98.6 degrees. If the temp rises above that set point homeostasis mechanisms kick in. when this happens the body releases sweat from sweat glands all throughout the body. In most cases when this happens a human is going under a lot of strenuous activity. even if it is cold out side the body can still build up enough heat to activate homeostasis mechanisms and produce sweat.
How does heat effect the human body?

What is the source of heat in the human body?

What part of the human body removes watersaltand body heat?

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.

What are inorganic nutrients that are not broken down by the human body or destroyed by heat?
There are several nutrients that are required by the human body that are not broken down by the body or destroyed by heat, including:* ...* ...* calcium* iron* ...
Are humans heat engines?
Humans are considered heat engines by some. Others do not believe that the human body can be considered a heat engine. However, most do on account of the heat production that comes from the human body, as well as, the amount of work the body is constantly doing.
What regulates heat?
A human body regulates its temperature by sweating and shivering. When the body is too hot, glands produce sweat which contains heat and evaporates, taking the heat with it. When a human is too cold, the body starts to shiver, a quick, repeated motion which generated heat from repeated muscle motion.
