All physiological and biochemical processes including immune function are temperature-dependent.  

All physiological and biochemical processes including immune function are temperature-dependent.  

Mammals have a constant core body temperature range but snakes and lizards depend on external temperature and behaviour such as basking and burrowing to influence their [[Body temperature|body temperature]] and hence their metabolism. The temperature range at which a snake's/ lizard's metabolism functions most effectively is referred to as the [[Preferred optimum temperature zone|preferred optimum temperature zone (POTZ)]].  The [[Preferred optimum temperature zone|POTZ]] may vary at different times of the year and even different times of the day.
