The lungs become black and breathing becomes hard. The lungs are protected by a series of defense mechanisms in different regions of the respiratory tract.
When a person breathes in, particles suspended in the air enter the nose, but not all of them reach the lungs. The nose is an efficient filter. Most large particles are stopped in it, until they are removed mechanically by blowing the nose or sneezing.
A ciliated epithelial cell is adapted to remove dirt from people's lungs.
Hairs in the Trachea that keep out dirt from the lungs.
Dirt and contaminants from the inspired air.
Dirt and chemicals in the air
to clear away mucus and dirt
Yes. Sand and dirt have very sharp edges....like little razors. Just living in a desert climate can be harmful to your lungs.
inside your lungs there are some cells called cillia they are little hairs that sway side to side hat remove dust and dirt from your lungs. when you smoke you are killing those cells thus all the dirt stays in your lungs making it hard for you to breath
When air with dust and dirt particles is inhaled through the nose, the tiny hairs and mucus in the nasal passages trap and filter out most of the particles. This helps prevent them from entering the lungs, keeping the respiratory system clear and healthy.
mucus
The mucous/slime traps dirt, and then you cough it up
Boiling dirt will not change its composition. The water will evaporate, leaving behind the same dirt particles that were there initially.
