respritory system
This occurs in the Lungs and the Alveoli.
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.

the lungs
The respiratory system is responsible for the exchange of gases between the atmosphere and the blood.
easy efficient exchange between air and blood
It takes place between the alveoli and the blood capillaries
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].
