To you all know the difference between oral and rectal thermometer’s is ?

TASTE

[Red Badger]

There actually is a ‘difference’.

Bulb shape

Since rectal tissues are fragile and easily ripped, rectal thermometers have a short, blunt, slightly rounded tip that reduces the risk of a rectal puncture or tear.

Oral thermometers have longer, thinner tips as a long and slender bulb exposes as much mercury surface area as possible. Exposing a larger surface area aids in obtaining an accurate temperature more quickly.
