Cards

Term
body heat
Definition
heat produced and heat transferred
Term
endotherms
Definition
  • higher MR to support heat generation BMR is 5x higher
  • insulation, reduces heat loss
Term
Ectotherms
Definition
  • low metabolism= low heat production
  • poorly insulated
Term
heterotherms
Definition
  • varying body temperature
  • some heat production
Term
2 types of heterotherms
Definition
  • temporal
    • varies with time
    • hummingbird
      • warm in day
      • cool at night
    • insects
  • Regional
    • over space
    • body regions
Term
Van't Holf Equation
Definition

Q10=(k2/k1)10/(t2-t1)<---> 10/10=1

 

Q10=(MR2/MR1)10/10

Term
The Thermoneutral Zone (TNZ)
Definition
temperature ranges in which no additional costs above BMR are incurred to keep body temp. (Tb) stable
Term
Insulation: the three F's
Definition
  • Fur
  • Feathers
  • Fat
