Answer to Question #119910 in Zoology for Shania kumar

Question

How is a birds respiratory system more efficient than humans

Answer 1

Birds take oxygen into their body tissues when they breathe in and when they breathe out. So, for every one bird breath, humans would need to take two. This makes birds super-efficient breathers.Secondly, the pulmonary capillaries in the bird have much thinner and more uniform walls, with more efficient gas exchange. Other advantages of the bird lungs over human lungs are that it utilizes a more efficient cross-current pattern of gas-exchange, and the bird has separated the ventilatory and gas exchange functions.
