Air sacs

Vedclass · Answer

(D) The respiratory system of birds is highly efficient and unique due to the presence of air sacs. Birds possess lungs that are connected to a system of nine air sacs that extend into the bones and other parts of the body. These air sacs do not participate in gas exchange directly but act as bellows to ensure a continuous,unidirectional flow of air through the lungs,allowing for efficient oxygen uptake even at high altitudes.
