Its nose, mouth and lungs of course.

Yes, and claws too. There are several cases of polar bear attacking humans.
Its mouth and its claws
All Polar Bears are left handed.

Respiratory system.
Yes. They have strong heads and thick bodies with a lot of muscles and strength that can easily knock down the polar bear by charging. The musk ox can also gore the polar bear too death, or knocking the polar bear with its head.
The diet depends on the habitat e.g. the polar bear will hunt and consume animals below it in the polar habitat e.g. seals, whereas the brown bear which resides in woodland habitats would feed on woodland creatures e.g. foxes.
Not much. Contrary from all the other bear species, the polar bear is almost entirely carnivorous. Mostly out of necessity, not much grows in the high arctic and nothing grows on the polar ice cap, which is where the polar bears live.
