Mucus and pathogens in the larynx and trachea are swept out by cilia, which are tiny hair-like structures lining the respiratory tract. These cilia move in a coordinated manner to push mucus upward toward the throat, where it can be swallowed or expelled. This mechanism is part of the body’s mucociliary escalator system, helping to keep the airways clear of debris and infectious agents.

How do chemicals in cigarettes affect the cilia in the trachea?
Cigarette smoke irritates cells in the bronchi and this irritation triggers special cells to produce a layer of mucus designed to trap the foreign particles irritating the cells. This layer of mucus is then suppose to be swept away by the Cilia, though the tar found in cigarette smoke slows the action of the cilia. This tar accumulates in the mucus layer, because the cilia are not able to respond due to the presence of this tar. In conclusion, the mucus layer will gradually grow over time because the cilia will not be able to sweep away the accumulated foreign particles.
What are 10 instering facts about the Trachea?
First: it is the "trunk" where air passes through to your bronchus and into your lungs (alveolar duct, alveolar sac, alveolus). Second: the trachea are made up of C-shaped rings of tough flexible cartilage. These rings of cartilage protect the trachea, make it flexible, and keep it from collapsing or over-expanding. Third: is the target for tracheal intubation, a medical procedure, for the critically injured. Allowing a medical provider to secure an open airway. Mainly because the trachea leads straight into the lungs. Forth: Because the trachea is mainly flexible it allows the oesophagus (which is attached to the back of the trachea) to expand when a bolus of food is swallowed. Fifth: The epidermal cells lining the trachea produce mucus which helps to capture things still in the air (fine dust and microbes). This is swept out of the air passageway by tiny ciliary cells, into the throat, where it is swallowed.
What sweeps mucus down your throat?
Mucus is swept down the throat primarily by the action of cilia, which are tiny hair-like structures on the surface of epithelial cells lining the respiratory tract. These cilia beat in a coordinated manner, moving mucus and trapped particles upward toward the throat, where it can be swallowed or expelled. Additionally, the process of swallowing helps clear mucus from the throat and keep the airways clear.
Why is it false that dust particles trapped in the mucus are swept away by tiny hair like alveoli?
It's false that dust particles are swept away by tiny hair-like alveoli because alveoli are the small air sacs in the lungs where gas exchange occurs, not structures designed for trapping dust. Instead, dust particles are trapped in mucus within the airways, and the cilia—tiny hair-like structures lining the respiratory tract—move the mucus upward toward the throat to be expelled or swallowed. Alveoli lack cilia and do not participate in this cleansing process.
How the goblet cells filter the air in the process of respiration n?
Goblet cells produce mucus which traps particulate matter in the air that we breathe in and is swept into the oral cavity to be either swallowed or spit out.
