What is the importance of pneumatic bones and air sacs in Aves ?​

Answer 1

Explanation:

Air sacs serve as internal compartments which hold air and facilitate internal air passage to allow birds to have a continuous flow of large volumes of air through the lungs as a way to increase oxygen exchange capacity and efficiency.

Pneumatic bones in birds are hollow. This helps to shed unnecessary weight that may hamper with the flight dynamics. The hollow spaces are filled with air, which provides structural rigidity as well as significantly reduced weight.

Answer 2

Pneumatic bones in Aves keep the body light and thus help in flight. Air sacs help in respiration and buoyancy
