Question

How does the respiratory system in birds differ from the mammalian respiratory system?

Answer 1

Answer:

Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.

Explanation:

Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.
