QUESTION
Evaporative heat loss by sweating is important in?
OPTIONS
(A) Dog
(B) Sheep
(C) Pig
(D) Man
ANSWER
(D) Man
EXPLANATION
Man is the correct option because humans have numerous functional eccrine sweat glands and rely substantially on evaporation of sweat for heat loss, especially during high environmental temperatures or exercise. Dogs have limited eccrine sweating and mainly use panting, while sheep and pigs have less effective sweating-based thermoregulation than humans.
