Body temperature is maintained by ______________?
Correct answer: D. all of the above
- A. Postural position
- B. Covering of the body
- C. Peripheral vasoconstriction
- D. all of the above
Explanation
Thermoregulation uses behavioural and autonomic mechanisms: posture and body covering alter heat loss, while peripheral vasoconstriction conserves heat by reducing skin blood flow. Thus all three listed measures can help maintain body temperature.
