Are bird lungs more efficient than mammal lungs?

WebDec 1, 2024 · Birds need a very efficient respiratory system, because they have such high metabolic rates, in order to sustain the enormous work output that they do when they fly. Birds have a one-way flow of air through their lungs. They don’t have the tiny air sacs – called alveoli – like we do. WebAlso, birds sometimes fly very high up, where there is very little oxygen in the air. Birds can fly up that high without any help, because of their special lungs. The bird's respiratory system takes up 20% of a birds's volume (our respiratory system takes up only 5% of our volume). Birds breath much more rapidly than humans do. WebMar 19, 2024 · Researchers have discovered that birds breathe with greater efficiency than humans due to the structure of their lungs -- looped airways that facilitate air flows that go in one direction. florida hurricane shutter grants
