body temperature regulation ch10 Flashcards
Regulator vs conform
regulator : has set point and maintains the variable within a consistent range
conform : has no set point and variable fluctuate with changes in the external envionment
Regulator example :
water salt=low concentarion
water salt=high concentration
conform example :
water temperature Low=body temperature low
water temperature high=Body temperature high
thermoregulation
a homeostatic process that maintains a steady internal body temperature despite changes in external conditions. Maintaining a body temperature within a tight range (between 36.5 to 37.5°C) allows for the enzymes and immune responses of the body to maintain proper functionality
thir mo requlation=التنظيم الحراري
thermo regulation
The ability of an animal to modify its behavior or physiology in order to maintain a range of body temperatures
temperature affect on :
1-rates of biochemical reaction
2-protein structure and function
3-rate of diffusion
how does animal generate body heat :
1-endotherm حرارة ثابته
2-ectotherm حرارة خارحية
N doh thirm/aac to therm
endo therm / ecto therm
endotherm called ____________ function :
warm-blooded
1-generate heat internally
2-regulate blood flow or adjust rate of metabolism
3-torpor and hibernation
tohr pir=motor inactivity/hi ber nation=سبات شتوي
torpor/hibernation
ectotherm called _________function
cold-blooded
1-Maintain body temperature through behavior
2-Get heat primary from the environment
Range of temperatures in endotherms in which no energy expenditure is needed to maintain body temperature

metabolic rate versus temperature
a person with a high metabolic rate will have a higher body temperature compared to someone with a lower metabolic rate. As body temperature goes up, so does metabolism
state of reduced metabolic activity during which the animal’s body temperature drops
hibernation
when does hibernation use ?
Used by animals to conserve energy during times when food is not readily available
might be short or long time and torpor
kin serve
conserve
method for regulation body temperature :
1-physical method=bear
2-cellular method=human being
3-behavioral method=
4-physiological method=dog
animal regulate body temperature by ____________
regulate blood flow
___________and_____________take advantage of evaporation
