mucus!!!!!!
mucus trap the dirt in the trachea!
It traps it using a filtering system of hair and mucous.
Mucus is the secretion produced by the respiratory system that traps dust and other inhaled foreign particles. It helps to protect the lungs by capturing these particles before they can reach deeper into the respiratory tract.
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.
This fluid is mucus, which is produced by the mucous membranes in the nose. It helps to trap and remove dust particles and other debris, preventing them from entering the respiratory system.
The sticky thick fluid that traps dust, germs, and other particles in the air is called mucus or phlegm. It is produced by the respiratory system to help filter out and remove harmful particles before they reach the lungs.
Cilia are tiny hairs that line the respiratory tract and help trap dust and foreign particles to prevent them from entering the lungs. These hair-like structures wave in a coordinated manner to move mucus and trapped particles out of the respiratory system.
The respiratory system, particularly the mucous membranes in the airways, traps germs and dust. Mucus produced by these membranes captures airborne particles, including pathogens, which are then removed from the body via cilia—tiny hair-like structures that sweep the mucus out of the lungs. Additionally, the immune system plays a crucial role in identifying and attacking trapped germs, helping to prevent infections.
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.
