Air gets moist and heated by the body's heat.
it is for foods,liquids,and air to pass .
Where air enters your vocal cords, makes them vibrate, and then makes sounds.
Then air moves in the trachea here it cleans the air.
The bronchi are at the lower end of the trachea. Here, it makes your air go to the left lung and air go to the right lung.
Small branches off the bronchi; push air into the lungs.
It is what carries oxygen to your lungs.
Your lungs are what hold oxygen so when you breath out you exhale CO2.
it changes volume were gases go in and out of from your lungs.
