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.

In the alveoli
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
The exchange of oxygen takes place in the alveoli. It is found in our lungs

In the lungs are small air sacs called alveoli. These alveoli are covered with blood capillaries. Oxygen and Carbon Dioxide diffuse through the alveolar capillary membrane. Oxygen diffuses from the alveoli to the blood capillary and carbon dioxide diffuses from the capillary to the alveoli and you breath it out of your body.
respiration ;)
When we exhale /blow out we push out all the carbon dioxide in our lungs!
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
