M, K decreased dramatically.

(247)

20. Overweight individuals with a large muscle mass experience greater heat

M, K production than underweight individuals and are therefore more susceptible to

(250) heat illness.

21. Heat exhaustion is caused by the sudden onset of thermoregulatory failure; this

M, K can lead to death if untreated.
