When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
alveoli take co2 from your blood and turns it into gas
oxygen enters the blood and carbon dioxide
it filters your lungs which causes you to exhale
it filters your lungs which causes you to exhale
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.

It happens in the alveoli of the lungs
It takes place between the alveoli and the blood capillaries
Carbon dioxide diffuses from the capillaries surrounding the alveoli into the lungs where it is exhaled, and oxygen diffuses into the capillaries surrounding the alveoli into the bloodstream where it will circulate throughout the body.
