through the lung ... the lungs and unloads its oxygen in the tissue capillaries. ...
lungs provide a large respiratory surface area but do not permit countercurrent.

They developed a variety of respiratory surfaces that all increase the surface area
... Frogs eliminate carbon dioxide 2.5 times as fast through their skin as they do
through their lungs. Eels (a fish) obtain 60% of their oxygen through their skin.
more when it's warmer because of the increase in their metabolisms. ... Why does
a bird's oxygen consumption decrease as the temperature increases? Answer: ...
For example, if this does not happen and carbon dioxide levels increase in the
body, pH levels ... Humans use only 1-2 % of their oxygen intake to keep
