If you unfolded all the folds and branches in your lungs, the area it would cover would equal about one half of a tennis court.
The Bronchus is the part of the airway that puts air into the lungs. There are two of them and they divide into many bronchioles which are then further subdivided into alveolar ducts to take the air into the lungs themselves.
lungs take oxygen into your body
the veins in your body take air from your nose into the lungs

The lungs
cuz u can see how much air ur lungs can take in
smoke has carbon dioxide your body can only take a certain amount of co2 we breathe in oxygen when too much carbon dioxide go into the system it cooks the lungs turning the lung black whereby you will have problems breathing
