Simply put, the gas exchange occurs in the lungs. More specifically, the blood exchange occurs at the avoli, the "air sacs" in the lungs where the surrounding capillaries can be oxygenated.
There are small sacs called Alveoli in the lungs. This is where the exchange occurs.

Alveoli
The exchange of gases occurs at the ends of the airways in the lungs. Here tiny sacs called alveoli connect with tiny blood vessels and here exhaust gas [carbon dioxide] is exchanged for fresh gas [oxygen].
--it is in the alveoli where the exchange of gases occur.. :))
respritory system
stomata, Lenticals and the thin coverings of roots
EF? (Extracellular fluid). i put a ? because i don't quite understand your question. Capillaries.
the blood vessel which allows gas exchange to occur is the capillaries
capillaries is where the exchange of materials occur such as; gases,nutrients, hormones, and so on.between the blood and the interstitial fluid.
During the stage of photosynthesis, the exchange of gases occur in the leaves.
The exchange of gases occurs at the ends of the airways in the lungs. Here tiny sacs called alveoli connect with tiny blood vessels and here exhaust gas [carbon dioxide] is exchanged for fresh gas [oxygen].
capillaries
gaseous exchange in the lungs takes place in the walls of the alveoli which are provided with a rich supply of blood vessels .the partial pressures of the gases .i.e. CO2 and oxygen in the atmosphere and the blood vessel is naturally perfect for the diffusion of gases.

respritory system
When the partial pressure between the alveoli and the blood, or between the blood and the tissues, is different - i.e. when a concentration gradient exists.

Yes, it does.
