The nose, pharynx, trachea, and bronchi.
No. It is warmed to near body temperature as it passes through the nose, throat, and bronchi.
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.
The mouth and nose serve to bring air in and out of the body. The trachea brings air from the nose and mouth to the lungs and vice versa. The lungs hold the bronchi which are groups of avioli .The alvioli serve as docking stations where blood cells can exchange co2 for oxygen they take to the rest of the body.
Air moves from the larynx into the bronchial tubes then enters the lungs and is filtered into oxygen and other components by the avioli. The oxygen goes to the blood, and the other molecules (nitrogen, argon,helium,hydrogen etc.) are breathed out.
