Answer 2

Answer:

They have special air sacs in addition to their lungs, with hollow bones that allow these gasses to flow around the body more easily. This means that one bird breath goes further and does more work than one mammal breath.

Explanation:

Their wings are attached to the thorax, their light organs, such as the lungs and sacs, are positioned high, and their heavy muscles are positioned centrally, all of which aid in flying. The birds' bodies are fashioned like a spindle to reduce air resistance during flight.
