Decreased Body Temperature
Endocrine Response
Nervous Response
Vascular Response
Adrenaline
Increased sensitivity
Surface Constriction
7
Adrenaline
Increased Sensitivity
Constriction
Blood shunt to brain and heart-Increased
resistance
Increased Metabolic Activity and Heartrate
Shivering
Increase in Temperature

Increased Body Temperature
Vascular Response
Integumentary and Endocrine Response
Sweat Glands activated
Surface Dilation
Convective Heat Loss
Evaporative Heat Loss

Change in Body Temperature
Increase
Decrease
Heat Loss -Vasodilation (Convection) -Sweating
(Evaporation)
Heat Gain -Shivering -Increased Blood Flow and
resistance (vasoconstriction)
