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.
The gas occurs by simple diffusion through the cells.
Blood gas exchange primarily occurs in the alveoli of the lungs, where oxygen from inhaled air diffuses into the blood while carbon dioxide diffuses out of the blood to be exhaled. This process is facilitated by the thin walls of the alveoli and surrounding capillaries, allowing for efficient gas exchange. Additionally, gas exchange occurs at the tissue level, where oxygen is delivered to cells and carbon dioxide is collected for transport back to the lungs.

Gas exchange can also be referred to as respiration. This process involves the uptake of oxygen and release of carbon dioxide in living organisms. It occurs in specialized organs such as the lungs in mammals and gills in fish.

That is a natural physiological process that occurs in the lungs. It is usually referred to as gas exchange, where the blood is enriched with oxygen as it looses most of its load of carbon dioxide.
