Oxygen enters the bloodstream and carbon dioxide leaves it.
When someone breaths in, they breath in oxygen which is carried around the body. Then when they breath out, they breath out carbon dioxide.

In the lungs, you have alveoli (grape like structures at the ends of the bronchioles) which are only one cell thick. This is where the gas exchange takes place.

Because there is oxygen in the alveoli and not in the blood stream, the oxygen diffuses across the wall of the alveoli and into the blood.

Blood saturated with CO2 runs from the body to the heart, to the lungs, where it passes through membranes in the 'alveoli'. Here it deposits the CO2 and uptakes O2 from the air you just breathed in. It then goes back to the heart and out to the rest of the body, muscles etc use up the O2 and back it comes, loaded with CO2

Where does gas exchange occur in the lungs?

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.
