The vacuum created by down-ward movement of the diaphram.
After passing through the bronchi, expired air moves into the bronchioles, which are smaller air passages within the lungs. From the bronchioles, the air then travels to the alveoli, where gas exchange occurs. Once the oxygen in the air is depleted and carbon dioxide is present, the expired air travels back through the bronchioles and bronchi, eventually exiting the body through the trachea and mouth or nose.

No. It is warmed to near body temperature as it passes through the nose, throat, and bronchi.
The correct order of structures in the respiratory passageways is as follows: air enters through the nose or mouth, travels down the pharynx, passes through the larynx, moves into the trachea, and then branches into the bronchi. From the bronchi, the air continues into smaller bronchioles and finally reaches the alveoli, where gas exchange occurs.
Air passes from the environment into the nose/mouth, through the nasopharynx and oropharynx, into the glottis, trachea, bronchi and its bifurcations, and into the alveoli of the lungs.
Two air passages which allow air to enter the body are the cilia and aveoli !!!
Air entering your body goes from the mouth and nose through the pharynx and into the trachea.
Mouth/nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and capillaries.
nose traps some of the dust particles
After air passes through the larynx, it enters your windpipe, or trachea. The trachea cleans the air again and channels it into the lungs through two large tubes called bronchi. The bronchi divide into smaller tubes and eventually lead to air sacs called alveoli. It is in the alveoli that oxygen moves into your blood and carbon dioxide moves out.
