The cilia trap dust and other particles as the air comes in Cillia are fan like projections in the linings of the tubes in the lungs. It is there job to waft the mucous cainting foreign bodies up to the back of the pharynx where it is swallowed to be destroyed in the stomach.
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. !!
Cilia are present all over the bronchial tree. Cilia push the foreign particles out wards. By this way cilia protect your respiratory system from damage by particles. Cilia also push the bacteria out from the respiratory tract.
cilia regain normal function
Cilia are tiny hair-like structures that line the respiratory tract and move in a coordinated manner to sweep mucus and foreign particles out of the airways. They function to protect and clean the respiratory system.
If the cilia in your respiratory system are damaged, it is least likely that you will effectively clear mucus, dust, and pathogens from your lungs. This can lead to an increased risk of respiratory infections and decreased lung function.
Respiratory system has got cilia all over the tracheobronchial tree. This protect the respiratory system from damage.
smoking causes tar to build up on the lungs, and the Cilia can't function properly.
Slowing down of cilia in smokers is dangerous because cilia play a critical role in clearing mucus and other toxins from the respiratory system. When cilia function is impaired, this can lead to a buildup of mucus and pollutants in the lungs, increasing the risk of respiratory infections and diseases like bronchitis and pneumonia.
Cilia are the tiny hairs that sweep dust and dirt out of the respiratory system.
mocos, cilia,
The particles trapped by the cilia in the respiratory system are moved upwards towards the throat where they are either coughed out or swallowed and eventually expelled from the body.
The cilia in the trachea move in a rhythmatic motion and the mucus produced by gland cells which traps foreign unwanted particles, like bacteria etc, is moved up to the pharynx where it is either coughed out or swallowed.
