We survive as the result of a large number of mutually interacting chemical and electrical arrangements. And typical proteins are carefully folded in elaborate ways to enable them to perform their enzymatic or hormonal functions. \n\nHigher temperatures characteristically increase reaction rates and decrease structural stabilty of folded proteins.  \n\nSo, if the high temperature you mention is high enough and lsts long enough, biochemical reaction rates will increase, deranging the reactions needed for cells to survive.  In addition, the 3D structure of proteins throughout the body will decrease, making enzymeatic function less effective, further disturbing the biochemical reactions we require to survive. \n\n======\ncellular heat shock stress reaction\n\nThere are also specific cellular reactions to stress. One is programmed cell death. It's not clear why suicide in response to stress is a reasonable way to proceed, though it may be a way to control dumping of cell contents into extracellular fluid. \n\nThe other is the increased production of a group of proteins called Heat Shock Factors (HSF). These have, it appears, a variety of functions, including chaperoning of folding proteins, and antigen presentation on cell surfaces for the immune system. Likely in conjunction with dendritic cells. There is current research and many clinical trials using the antigen presenting function of heat shock proteins as a tumor specific vaccine. The technique shows considerable promise in cancer and perhsps even in some auto-immune diseases.  \n\n========\noverall \n\nJust what cellular system(s) will fail first, and what will follow, probably depends on how high the termperature goes and remains. As well, we all have biochmical differences, and differing tolerances for chemical breakdowns.\n\nAs cells fail, organ systems will begin to fail as well. If enough do so, unconsciousness and death will follow.

Properties of homeostasis\n\nHomeostatic systems show several properties:\n\n    * They are ultrastable: the system is capable of testing which way its variables should be adjusted.\n    * Their whole organization (internal, structural, and functional) contributes to the maintenance of equilibrium.\n    * They are unpredictable: the resulting effect of a precise action often has the opposite effect to what was expected.\n\nMain examples of homeostasis in mammals are as follows:\n\n    * The regulation of the amounts of water and minerals in the body. This is known as osmoregulation. This happens in the kidneys.\n    * The removal of metabolic waste. This is known as excretion. This is done by the excretory organs such as the kidneys and lungs.\n    * The regulation of body temperature. This is mainly done by the skin.\n    * The regulation of blood glucose level. This is mainly done by the liver and the insulin secreted by the pancreas.\n\nIt is important to note that while organisms exhibit equilibrium, their physiological state is not necessarily static. Many organisms exhibit endogenous fluctuations in the form of circadian (period 20 to 28 hours), ultradian (period <20 hours) and infradian (period > 28 hours) rhythms. Thus even in homeostasis, body temperature, blood pressure, heart rate and most metabolic indicators are not always at a constant level, but vary predictably over time.\n\nHomeostasis in the human body\n\nAll sorts of factors affect the suitability of the human body fluids to sustain life; these include properties like temperature, salinity, and acidity, and the concentrations of nutrients such as glucose, various ions, oxygen, and wastes, such as carbon dioxide and urea. Since these properties affect the chemical reactions that keep bodies alive, there are built-in physiological mechanisms to maintain them at desirable levels.\n\nHomeostasis is not the reason for these ongoing unconscious adjustments. It should be thought of as a general characterization of many normal processes in concert, not their proximal cause. Moreover, there are numerous biological phenomena which do not conform to this model, such as anabolism.

Since you had recently suffered from flu, and having sat around during the party in the night where you could have lost your body’s core temperature.  Your body had reacted to it by curtailing the circulation of the skin (goose pimples) and other non essential parts of the body so conserve heat of your body.  But once you were back in your bed, the outside temperature being returned back to normal, blood would have started flowing out to the skin, which was so far curtailed by your body mechanism.  This caused the body losing heat and this started the shivering and this way the muscular activity generated had built up your core body temperature while diverting your blood to the splanchnic pool (the blood pool which supplies to the viscera of the body).  \n\nNow since your blood was pooled in your visceral area and therefore could not reach the brain in sufficient quantities while you were straining to void your bladder, it caused you a spell of dizziness/fainting.  MICTURATION SYNCOPES are known to occur, but in the old and the frail, after prolonged illnesses, or in those with obstruction like BPH (Benign Prostate Hypertrophy) where one has to strain more to pass out urine through the obstructed tract.   \n\nDo not be unduly worried.  Start taking plenty of warm fluids, soups etc.  Keep your body well protected from cold and do not jump out of the bed, get out slowly and do not hurry.  Do not strain too much while standing to void your bladder.  Good luck.

we get goosebumps when our bodies acknowledge that the external temperature has dropped too low and our body is losing to much heat which can lead to hypothermia. the goosebumps are actually our skin closing our pores to help hold in heat and there fore keeping out internal temp normal

The skin would become very soft , sodden and tear easily.  If decomposition is slowed down due to low temperatures the skin of the hands and feet can peel off like gloves.  Later the hair will become loose and toe/finger  nails will become detached.\n\nNormal decomposition  would begin internally although this would be slowed down if the temperature of the water was very cold.  The body would become bloated as the internal organs such as the gut decompose first.  Rigour mortis (stiffness of the body) would set in and then disappear.  The outside of the body would probably be attacked by marine life hastening the exposure of the inside of the body to the salt water.\n\nSofter parts of the body such intestines, stomach, liver and heart blood decompose first.  This is followed by the lungs, liver, brain, kidneys and bladder.  Muscle and the uterus decompose last of all.\n\nIf the body were washed around in strong currents it is likely to be washed ashore.  If the body stayed in the water the limbs are likely to become detached in due course.  Flesh will break down into slime  and the skeletal frame will collapse.

Your body will go into starvation mode and start to shut down.  Your body will retain all it's energy for making your brain and heart work, but at some point those would shut down, too.

Homeostasis: resistance to change\n\nA person threatened by the environment (or informed of an approaching pleasure or danger) prepares for action. The body mobilizes reserves of energy and produces certain hormones such as adrenalin, which prepare it for conflict or flight. This mobilisation can be seen in familiar physiological reactions. In the presence of emotion, danger, or physical effort the heart beats faster and respiration quickens. The face turns red or pales and the body perspires. The individual may experience shortness of breath, cold sweats, shivering, trembling legs. These physiological manifestations reflect the efforts of the body to maintain its internal equilibrium. Action can be voluntary--to drink when one is thirsty, to eat when hungry, to put on clothing when cold, to open a window when one is too warm--or involuntary--shivering, sweating.\n\nTo know more and all about it .... visit. ... and hope this helps

you need to see a doctor. at temperatures this high for such a period of time, your enzymes in your body begin to denaturize, or unwind. since your young, this probally doesnt make too much sense, but it can become a bad situation. call someone, your grandma, aunt, uncle, family friend. having a temperature of 102 or more can be dangerous if not controlled. take a NSAID such as tylenol or advil, alternating them. your best bet would be to use motrin. drink lots of water and take vitamin c, if you have any, if not, eat lots of fruit, but most importantly, get some help from a medical professional, for your healths sake!

Our bodies remain at a temperature of 37deg celcius for optimum functioning and health. When we are cold our bodies are in danger of loosing that vital heat, so it has developed various methods to stop this from happening.\n\n1) we shiver. This generates heat, as the vibrations of our body cause friction. \n\n2) out body hair stands up on end (goose pimples) to trap air next to our body and form a layer of insulation around us, preventing heat from escaping.\n\nThese two functions are enough to replace any heat lost to the surroundings which have triggered these reactions.\n\nOur boby will remain at 37deg celcius whether we are standing in a steam room or ice box.

Animals capable of temperature regulation within a given range are deemed homeotherms (alternatively homiotherms or homotherms). They have the ability to regulate temperature via negative feedback control.\nTemperature is controlled in a variety of ways in these animals.\nThe hypothalamus acts as a receptor in regulation, by detecting fluctuations in temperature. These receptors are better known as thermoreceptors.\nSkin also possesses thermoreceptors which can detect the temperature of the external environment. This information is relayed to the hypothalamus which can in turn transmit nerve pulses for corrective mechanisms to occur.\nIncreased sweating is a corrective response aimed to reduce the temperature of the organism.\nVasodilation is a corrective response where the blood vessels close to the skin surface become more dilated, meaning their is a larger surface area for heat to be lost of the external environment from the blood vessel carrying over-heated blood.\nVasoconstriction is the opposite of this and occurs when temperatures in an organism drop. The blood vessels become constricted so that minimal heat loss occurs.\nThe hairs on your body also play an important role in temperature regulation. A corrective response can occur where the hairs 'stand on end', and trap a layer of air between the hair and the skin. This insulation of warmer air next to the skin reduces heat lost, while a thin layer of insulation would increase heat loss.\nOther corrective mechanisms are involved, such as a drop in metabolic rate and shivering when temperatures drop.

Homeostasis basically relies on negative feedback mechanisms: if there is a deviation from the norm, eg an increase in blood glucose level, this will set in effect a chain of events that will bring the level back to the norm, at which point the lack of the original deviation switches off the events originally put into place, hence its called NEGATIVE feedback.

Homeostasis is the property of an open system, especially living organisms, to regulate its internal environment to maintain a stable, constant condition, by means of multiple dynamic equilibrium adjustments, controlled by interrelated regulation mechanisms. The term was coined in 1932 by Walter Cannon from the Greek homo (same, like) and stasis (to stand, posture).\n\nOverview\nThe term is most often used in the sense of biological homeostasis. Multicellular organisms require a homeostatic internal environment, in order to live; many environmentalists believe this principle also applies to the external environment. Many ecological, biological, and social systems are homeostatic. They oppose change to maintain equilibrium. If the system does not succeed in reestablishing its balance, it may ultimately lead the system to stop functioning.\n\nComplex systems, such as a human body, must have homeostasis to maintain stability and to survive. These systems do not only have to endure to survive; they must adapt themselves and evolve to modifications of the environment.\n\n[edit]\nProperties of homeostasis\nHomeostatic systems show several properties:\n\nThey are ultrastable: the system is capable of testing which way its variables should be adjusted. \nTheir whole organization (internal, structural, and functional) contributes to the maintenance of equilibrium. \nThey are unpredictable: the resulting effect of a precise action often has the opposite effect to what was expected. \nMain examples of homeostasis in mammals are as follows:\n\nThe regulation of the amounts of water and minerals in the body. This is known as osmoregulation. This happens in the kidneys. \nThe removal of metabolic waste. This is known as excretion. This is done by the excretory organs such as the kidneys and lungs. \nThe regulation of body temperature. This is mainly done by the skin. \nThe regulation of blood glucose level. This is mainly done by the liver and the insulin secreted by the pancreas. \nIt is important to note that while organisms exhibit equilibrium, their physiological state is not necessarily static. Many organisms exhibit endogenous fluctuations in the form of circadian (period 20 to 28 hours), ultradian (period <20 hours) and infradian (period > 28 hours) rhythms. Thus even in homeostasis, body temperature, blood pressure, heart rate and most metabolic indicators are not always at a constant level, but vary predictably over time.\n\n[edit]\nMechanisms of homeostasis: feedback\nMain article: Feedback\n\nWhen a change of variable occurs, there are two main types of feedback to which the system reacts:\n\nNegative feedback is a reaction in which the system responds in such a way as to reverse the direction of change. Since this tends to keep things constant, it allows the maintenance of homeostasis. For instance, when the concentration of carbon dioxide in the human body increases, the lungs are signaled to increase their activity and expel more carbon dioxide. Thermoregulation is another example of negative feedback. When body temperature rises (or falls), receptors in the skin and the hypothalamus sense a change, triggering a command from the brain. This command, in turn, effects the correct response, in this case a decrease in body temperature. \nIn positive feedback, the response is to amplify the change in the variable. This has a destabilizing effect, so does not result in homeostasis. Positive feedback is less common in naturally occurring systems than negative feedback, but it has its applications. For example, in nerves, a threshold electric potential triggers the generation of a much larger action potential. (See also leverage points.) Blood clotting and events in childbirth are other types of positive feedback. \nSustainable systems require combinations of both kinds of feedback. Generally with the recognition of divergence from the homeostatic condition positive feedbacks are called into play, whereas once the homeostatic co

u cant decrease sweat and ur not supposed to. Sweatin is metabolic process ur body does when it heats up to much.If u dont sweat the high body tempature would make u sick like when u get fevers.
