Question
- A. Increases body temperature
- B. Cools the body through evaporation
- C. Reduces blood flow to the skin
- D. Stimulates shivering
Answer
The correct option is Cools the body through evaporation. This answer is correct because it matches the approved learning objective to describe vasodilation and sweating as responses when body temperature is too high in the subtopic Control of body temperature (biology only).
Explanation
The correct option is Cools the body through evaporation. Cools the body through evaporation is correct because it directly supports the approved learning objective to describe vasodilation and sweating as responses when body temperature is too high. This belongs to the subtopic Control of body temperature (biology only) within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Control of body temperature (biology only).
Common mistake
Misunderstanding Vasodilation
Students often confuse vasodilation with vasoconstriction, thinking both processes help cool the body.
Remember that vasodilation is the widening of blood vessels, which increases blood flow to the skin and helps release heat when body temperature is too high.
