mucus!!!!!!
mucus trap the dirt in the trachea!
mucus
It traps it using a filtering system of hair and mucous.
Mucus traps dirt and bacteria.
Cilia are the tiny hairs that sweep dust and dirt out of the respiratory system.
The respiratory system has a number of nonspecific defenses against disease. The hairs of the nose trap dust and pathogens. Mucus in the upper and lower respiratory system traps foreign bodies and pathogens. The cilia constantly move the mucus with this trapped material out of the system. The cough and sneeze reflexes also offer protection.
The tiny hairs that trap dust and pollen are known as cilia. Cilia traps dust and pollen in the nose before it reaches the lower respiratory tract and lungs.
When look at the function of cilia in the immune system, you mainly refer to the cilia present in the respiratory system. Cilia, along with mucus, are part of the innate immunity your body has. Mucus in respiratory tubes traps most microbes and dust that get past the nasal filter (nasal hair). Cilia on cells lining the tubes sweep mucus upward and out of the system. !!
They avoid dust entering the nostrils.
The mucus layer protects the respiratory tract by trapping bacteria and dust, not allowing them to enter the body. Mucus filters the air during inhalation and keeps the tissues from becoming too dry.
It really is stored in the nose. The lining of the respiratory tract (including the nose) produces a mucous (phlegm). This traps dust and other stuff that doesn't belong further in the tract. This is moved slowly out with its' dust.
I believe it is the epiglottis, it covers the trachea preventing you from aspirating fluid and such...
Mucus in the respiratory tract traps disease-causing bacteria.
