Question

where does exchange of gases takes place in lungs
​

Answer 1

Explanation:

Exchange of gases take place in alveoli.

Answer 2

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
