Yep.
Gas exchange occurs across the respiratory membrane of the alveoli; however, the short answer is simply alveoli
The gas occurs by simple diffusion through the cells.
Alveoli
The organ that has alveoli wrapped in capillaries for gas exchange is the lungs. Alveoli are tiny air sacs where oxygen from inhaled air diffuses into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. This efficient gas exchange process is facilitated by the close proximity of the alveoli to the surrounding capillaries.
Alveoli is where gas exchange occurs.
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.
Destruction of alveoli reduces the surface area for gas exchange
The actual air exchange in the lungs takes place in the alveoli, which are tiny sacs at the end of the bronchioles. Oxygen from the inhaled air passes through the walls of the alveoli and into the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled.
