   Hello Guys How are you?? Today i was studying physiology Body temperature measurement and i saw in general and in normal conditions that the oral cavity temperature is lesser than rectal temperature but why the oral temperature is lesser than rectal temperature?? And what is the reason?

   Ambient air temperature is usually lower than body temperature, and as air moves through the mouth it can evaporate saliva. Both factors lower oral temperature.
   Drinking cool liquid really lowers temperature for a short period.
   
   The anal cavity does not have ambient air moving through it. No drinking either.
