It is safe to breathe through the mouth, but it is a tiny, tiny bit better to breathe through the nose.
If you breathe through the nose, the air has to travel longer before it reaches the lungs. And that longer joúrney means that any dust in the air has had a better chance of getting caught on the inner surface of the airways, the air will be closer to body temperature, and if the air is dry, it'll have picked up some moisture along the way as well too. Not actually required, but things that'll make life easier on the lungs.
No, whatever feels natural for you, do.
Through your nose and mouth.
Like humans, chipmunks breathe air into their lungs through their mouth and nose.
It next passes into the lungs when we breathe in, and out through the trachea, the larynx and the mouth and nose when we breathe out.
using their skin :})
Seals are mammals. They Breathe air with lungs, through mouth and nostrils. And they have to Breathe while sleeping just like you and I.
The mouth provides more air and a better pathway to the lungs.
it goes into the lung just the same as if you were to breathe through your mouth.
The mouth, nose, pharynx, larynx and trachea.
Elephants breathe through the mouth or trunk (which is just a very long nose) . The air then goes to the lungs, which function just like ours.

Because there is no hair or mucus (I know it's gross if you imagine it) to block out dirt in the air that we breathe in. Whereas in the nose, there are. And the air we breathe in through the mouth will go down to our throat and cause our throat to be dry and we will develop cough or flu (maybe).
Physically, they breathe through their noses or mouths. In the Arctic, they come up for air through what are sometimes called 'blowholes'. And sometimes, Polar bears are waiting for them there.
