The body compensates for increased environmental temperature by:

 

a) decreasing salt retention

 

b) increasing respiration rate

 

c) increasing heart rate

 

d) increasing water lost through skin

 

 

Explanation

 

The body compensates for increased environmental temperature by sweating and losing water through the skin. Respiration and heart rate increase during exercise in response to internal demand for more oxygen. Salt retention has little to do with environmental temperature.

 

a) decreasing salt retention, incorrect.

 

b) increasing respiration rate, incorrect.

 

c) increasing heart rate, incorrect.

 

d) increasing water lost through skin, correct.
