they exchange in the aveoli and capillaries
The exchange takes place within the lungs.
perfusion
Gaseous exchange is the movement of oxygen in the body, it takes place in the lungs through diffusion by the alveolar surface. There are millions of alveloi in the lungs, which gives it around 70m2 of exchange surface.

in mammals, what structure ensures the exchange substances between the embryonic and material blood circulation
stomata
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.
i believe its gap junctions
To Provide maximum surface area for exchange
