Quick explanation
Explain (HT only) how vasoconstriction and shivering help raise body temperature
- This point belongs to The human nervous system, especially Control of body temperature (biology only).
- You need to be able to explain (HT only) how vasoconstriction and shivering help raise body temperature.
- The key ideas to know are body temperature, shivering, and vasoconstriction.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Control of body temperature (biology only) to exam-style questions, flashcards, and revision notes for The human nervous system.
Quick student answer
How do you explain (HT only) how vasoconstriction and shivering help raise body temperature?
Direct answer
In Biology, this page helps you answer questions about (HT only) how vasoconstriction and shivering help raise body temperature within The human nervous system. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are vasoconstriction and shivering.
Key terms
- vasoconstriction: The narrowing of blood vessels, which reduces blood flow to the skin and helps to conserve body heat when temperatures are low.
- shivering: A rapid, involuntary contraction of muscles that generates heat to raise body temperature when it is too low.
Common trap
Misunderstanding Vasoconstriction: Remember that vasoconstriction narrows blood vessels to reduce blood flow to the skin, conserving heat, while vasodilation increases blood flow to release heat.
