by breathing it in? I'm pretty sure its obvious but the fact that you had to ask makes me hesitant as I now feel there's something way more complicated

Answer 2

Bears are mammals, which means they breathe air. Air enters into the bear's lungs and oxygenates his blood, then the bear exhales carbon dioxide. Humans follow the same process of respiration.

Answer 3

Polar bears get oxygen into their bloodstream in essentially the same way that humans, and all mammals, birds and reptiles, do. When polar bears breathe, their lungs fill with a mixture of gases including oxygen. The polar bear's body absorbs some of the oxygen into the blood through the little air sacks in the lungs called alveoli.
