Answer Details

In order to provide oxygen to the body and remove carbon dioxide, exchange of gases occurs in the respiratory system of animals. In birds, exchange of gases takes place in their unique respiratory system which includes air sacs. These air sacs are connected to the lungs and allow the air to flow in one direction, providing a continuous supply of fresh oxygen. The exchange of gases, i.e., the uptake of oxygen and release of carbon dioxide, primarily occurs in these air sacs, which are contained in option IV.
