the introduction of the respiratory system
First we intake the air that have oxygen in to our body the air travels down through trachea tube into the lung through bronchi, the bronchus are attached by billions of alveolus and the alveolus also attached by the capillaries.
then the oxygen in the air diffuse from alveoli to the poor oxygen blood cell through the capillaries, the blood cell becomes oxygenated and travel out of the lungs through out the parts of the body. After that it comes back to the lung again and diffuse the CO2 to the alveoli though capillaries and the CO2 gets out from your body by the time you exhale. It works as a cycle.
