Common mistake
Misunderstanding Vasodilation
Students often confuse vasodilation with vasoconstriction, thinking both processes lower body temperature.
Remember that vasodilation involves the widening of blood vessels, which increases blood flow to the skin, allowing heat to escape and thus lowering body temperature.
