polar bears have a much longer muzzle (nose) than humans do. This means that the air that is inhaled has more time to get warmed up and rehydrated in a polar bear nose than it does in a human nose.

Explanation:

The respiratory system uses the lungs, blood, heart, veins and arteries to take in oxygen, transport it around the body and breathe out carbon dioxide.polar bear can close off its nose, in order to stop water from entering it when swimming.
