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.
Capillary system is where gas exchange occurs
respritory system
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].
There are two place where this process occurs: i) the Lungs, and ii) the Capilliaries.
Alveoli- these are the small sac-like structures where gas exchange occurs with the blood. Its creates an ideal site for gas exchange between the air in the lungs and the blood in the capillaries.
