Students have asked these similar questions
Describe structural and functional differences between gills and lungs (ie. know the anatomy of lungs and gills). Why are birds’ lungs more efficient at removing O2 from the air compared with mammalian lungs?
Please describe 3 ways animal respiratory systems have evolved in order to maximize the exchange of O2 and CO2 across their membranes
Explain how ventilation in bird lungs differs from that in mammalian lungs, including the advantage of the avian system over the mammalian one.
