Trachea have cartillage rings which support it. And the Alveoli has large surface area for diffusion and its moist and thin.
alveoli
There is more space that is occupied by H20 in the alveoli than the trachea. (BTPS - body tempertaure ,pressure saturated)
Trachea> Bronchii> Bronchioles (smaller branches of bronchii) > Alveoli

No, the trachea is a passageway for air to travel to and from the lungs. Oxygen and carbon dioxide are exchanged in the alveoli of the lungs, where they diffuse across the walls of the alveoli and capillaries.
It isnt. There is no gas exchange in the trachea this takes place at the alveoli.
a nose
Air moves from the nasal cavity to the nasopharynx, oropharynx, larynx, trachea, bronchi, bronchioles, and finally arrives in the alveoli.
5 parts of the respiratory system are as follows: lungs, trachea, heart, larynx, pharynx.
farts
Air enters trachea (wind pipe) via nostrils. From trechea it goes into left and right bronchus. It is then channeled into progressively narrower channels and finally it reaches alveoli where gaseous exchange occurs. This whole event is assisted by movement of diaphragm and of ribs.
