respiratory system


When we breathe all gases goes inside like nitrogen, hydrogen, oxygen and carbon-dioxide then they go to trachea [wind pipe] from there it goes to bronchioles then it goes to bronchi from bronchi it goes to alveoli there it takes oxygen and sends other gases in the same way and the gases except oxygen comes out.
