Bronchioles: Thousands of tiny tubes that branch out from the two bronchi Alveoli: Thousands of tiny air sacks inside the lungs. The respiratory system drives respiraiton in which the oxygen is cleaned, waste CO2 is gotten rid off and cells get energy.
The air goes in through the nose
It goes down to the lungs through the trachea
The Oxygen passes from the trachea threw the two bronchi to both lungs.
From the bronchi the air goes to bronchioles that tale the air throughout the lungs.
Once is gets to the alveoli the gaseous exchange hapens which is when CO2 and O2 are exchanged in the alveoli. Then the waste CO2 is disposed and the clean oxygen goes threw the veins to the body.
