(a) Heat loss by conduction/ convection from the blood vessels in the body skin to the cold water: the cooler blood leaving skin enters general circulation cooling the whole body
(b) - No sweating: this eases heat produced through metabolism
- Vasoconstriction; thus less blood flowing to the skin reducing heat loss
- Shivering - involuntary muscles contractions to generate heat
