Thermoregulation Flashcards
1
Q
Vasoconstriction
A
In cold temp Arteriols constrict
Less blood flow so retains heat
2
Q
Vasodilation
A
Warmer temps arteriols dilate
More blood flows to skin
Adds heat loss
3
Q
Pilorection
A
Hair feather stands
Traps air
Reducing heat loss
4
Q
Pilorelaxtion
A
Body hair lowers so air can flow
Allowing evaporation
