What is the ability of the human body to maintain a constant body temperature?

∙ 11y ago
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.

∙ 11y agoThe hypothalamus is the processing centre in the brain that controls body temperature. It does this by triggering changes to effectors, such as sweat glands and muscles controlling body hair. Heat stroke can happen when the body becomes too hot; and hypothermia when the body becomes too cold.

Is it true that cells can regulate what they need or don't need to maintain their own health?
Human cells do have the ability to regulate what they need or don't need to maintain their own health. Cells are found all throughout the body.
Why mammalian enzymes have optimum temperatures of approximately 40oC whereas plant enzymes have optimum temperatures of 25oC?
Human body temp is constantly maintained at 37 degrees so our enzymes have evolved to work best at this 'warm' temperature . We like nearly all other mammals are warm blooded. Plants do not have to keep their temperature constant and generally exist in colder conditions and can tolerate far greater deviations in temperature hence their enzymes tend to work best at lower temperatures.
What functions does water play in the body?
It dissolves substances within the body; carries nutrients from place to place, and helps maintain body temperature.
What is color consistency?
Colour consistency is the variation of the dominant or contrasting wavelength in identical lamp samples. It is also what allows a human to see the same colour in a variety of situations.Colour constancy is the brains ability to assign a constant colour to a surface. For example Granny Smith apples will have a constant green colour.
What does an Atam maintain?
Human body parts as in the eyeball and your facehole
Why are four types of tissue important for the human body?
Homeostasis: the ability of an animal to maintain a constant internal environment
Why the human body temperature always remains constant in normal person?
why the human body temperature always remains constant in normal person
What is the function of alkaline in the human body?
It is storage for excess nutrients in the body that can be used later, when needed. It is used to help maintain constant body temperature and is a factor in over-all
The ability to maintain stability by responding to stimuli that disrupt normal functioning is called?
In reference to the human body, I would call this the innate ability to maintain homeostasis.
What is the definition of homeostasis?
Homeostasis is the ability of an organism to maintain internal stability and balance in response to external changes. It involves the regulation of various physiological processes to keep conditions within a narrow range that is conducive to life.
How does arthritis affect the human bodys ability to maintain homeostasis?
it will stop the joints from growing
Which is not a characteristic of the human amniotic sac?
plato (B: maintains a constant temperature)
What does the human body do to maintain homeostasis?
Homeostasis is the term we use to describe the constant state of the internal environment.
How does homeostasis impact the human body?
Maintain a normal value of certain body temperature.
What do greenhouse gases do to the world?
Maintain a stable global temperature. Human induced global warming increases the global average temperature.
What form of cellular transportation helps human cells maintain a constant sodium and potassium concentration?
A cell membrane pump
Why is it important for mammals to maintain a constant body temperature?
Homeostasis means your body regulates things like temperature, for example. If our (or any animal's) body did not maintain hoemeostasis, then everything would be out of controll, and we would get very sick, very fast.
