Terms in this set (21)Why is it so important to maintain body temperature at 37 degrees C (98.6 degrees F)? chemical reaction rated in the body will by affected What events cause the body's temperature to change (4)? exercise Skin ensures that the amount of body heat lost = amount of body heat produced. How? when body temperature rises ABOVE the set point, there are methods that may be used to lower temperature. What are the methods used to lower body temperature (4)? radiation What happens in radiation? heat escapes from warmer surfaces to cooler surroundings What happens in conduction? heat moves from body directly into molecules of cooler objects that are in contacts with body's surface What are examples of conduction? flipping
a pillow What happens in convection? heat is lost to air and is replaced by cooler air moving toward the body What are examples of convection? sitting in front of fan or air conditioner What happens in evaporation? eccrine glands releasing sweat onto surface; as fluid changes from liquid to gas, it carries away the heat What environmental scenarios causes these mechanisms NOT to work (2)? humid days What mechanism has a decrease in effectiveness on humid days? evaporation What mechanism has a decrease in effectiveness on extremely hot days? radiation What happens when the mechanisms do not lower body body temperature? leads to hyperthermia What happens to blood vessels when the body temperature drops below the set point? constrict to reduce heat loss through radiation, conduction, and convention What happens to sweat glands when the body temperature drops below the set point? are inactive What is the benefit of shivering? generates heat What does the nervous system do if body temperature continues to drop? stimulates muscles to contract which results in shivering What causes hypothermia? prolonged exposure to cold renders the body helpless after some time What are symptoms of hypothermia (6)? shivering and coldness How many degrees below normal can the extremities withstand? 20-30 degrees F Sets with similar termsTHERMOREGULATION53 terms guerraj6045 Fun. of Nursing Thermoregulation38 terms Gabster204 18.6 Body Heat and Thermoregulation23 terms Maria_Amezquita9 Temperature Regulation40 terms angelabarcax3 Sets found in the same folderSteps of Intramembranous Ossification6 terms tcli Unit 5 : The Muscular System Super Quizlet406 terms tcli Steps of Endochondral Ossification6 terms tcli Unit 6: The Nervous System - 1) Divisions of the N…73 terms tcli Other sets by this creatorNeuroglia6 terms tcli Vocab Set S30 terms tcli Spinal cord7 terms tcli Cindy's Capital Quizlet24 terms tcli Verified questions

Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death. Hypothermia is often caused by exposure to cold weather or immersion in cold water.
How does your body react when the temperature decreases?How does the body respond to a decrease or increase in core body temperature? If the temperature decreases:The blood vessels supplying the skin constrict (vasoconstriction) resulting in less blood flow to the skin surface and hence less energy (by heat) is lost.
