Mucus and cilia. The dirt and other impurities that enter the respiratory tract are trapped by the mucus, in order not to enter the lungs and its structures. But the accumulation of too much mucus in the trachea would impede us from breathing, so the cilia sweep the mucus out of the trachea.
mucus!!!!!!mucus trap the dirt in the trachea!
Trachea
In tetra pod anatomy, the trachea, or windpipe, is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
Bronchitis damaged your cilia which is very dangerous. the function of cilia is to move the mucus out of your trachea but since there will be no cilia the mucus will accumulate in the lungs and will reduce the air being inhaled which can suffocate you. u cannot exercise. your stamina will go down and things like that
The term bronchitis is used for a non-specific inflammation of the bronchi, the branches of the trachea that extend into the lungs.
Helps expell mucus from trachea
It traps bacteria and dust.
In the lumen of the trachea, this is the area that is in contact with the air coming in.Cilia are projections on the end of columnar epithelial cells that line the trachea (windpipe), they are responsible for beating (in a 'waving' motion) mucus filled with debris up the trachea out of the lungs and to the epiglottis where it can be swallowed and broken down safely in the stomach.
Mucus secreted by goblet cells trap the foreign particles. Cilia push the particles out wards. This protects your lungs from damage by the foreign particles.
mucus- mucus in the lungs makes breathing difficult
