Question 4: When you exercise strenuously, your body produces excess heat. Describe what your body does to help prevent your temperature from rising excessively, and explain why the body's response is effective.
You responded:
Complete
Student indicates that the body keeps its temperature from rising through sweating or by blood vessels dilating and states how these are effective.
Partial
Student indicates that the body keeps its temperature from rising but does not explain fully how the mechanism works.
Unsatisfactory/Incorrect
Student provides little or no evidence of knowledge of any mechanism for losing heat during exercise.
