SPUTUM
The lay person's term for that is phlegm.
Phlegm
The mucus of the trachea is expelled from the respiratory tract through a process called mucociliary clearance. Cilia, tiny hair-like structures lining the trachea, move the mucus upwards toward the throat. Once it reaches the throat, the mucus can be swallowed or coughed out. This mechanism helps keep the airways clear of dust, pathogens, and other debris.
Mucus is pushed to the throat from the respiratory tract, primarily through the action of cilia—tiny hair-like structures on the surface of respiratory cells. This process helps trap and clear dust, pathogens, and other particles from the airways. Once in the throat, mucus can be swallowed or expelled through coughing. Additionally, mucus in the digestive system aids in lubrication and protection.
Ciliated epithelial cells produce mucus, which helps to trap and remove foreign particles and pathogens from the respiratory tract. The cilia on the cell's surface then move the mucus along to be expelled or swallowed.
Black particles in mucus are often the result of environmental pollutants such as soot or smoke being inhaled into the respiratory system. These particles can accumulate in the mucus and be expelled through coughing. It is important to avoid exposure to such pollutants to reduce their presence in mucus.
Actually, the body region where a ciliary escalator helps to sweep microbes trapped in mucus away is the respiratory tract, specifically in the lungs. The cilia lining the respiratory tract beat in a coordinated manner to move mucus and trapped microbes up and out of the airways.
Mucus is a substance commonly expelled from the compound alveolar gland. It helps to trap foreign particles and bacteria, enabling the body to remove them from the respiratory system.
mucus!!!!!!mucus trap the dirt in the trachea!
Mucus in the nose and trachea traps foreign particles and bacteria. The cilia, tiny hair-like structures in the respiratory tract, move the mucus and trapped particles upwards to be swallowed or expelled. This process helps to protect the lungs and respiratory system from harmful invaders.
Mucus is produced by the goblet cells, in the airways dust particles etc will stick to the mucus, cilia cells then use energy to sweep the mucus up back up through the trachea, where we can swallow it and dust particles and pathogens etc can be broken down by enzymes in the stomach, or we can expell it by sneezing or coughing.
Boogers don't really have any benefits. Boogers are the results of the benefits of snot (mucus) in your nose. Dust particles get trapped in the moist mucus, dry and become boogers. Boogers are then expelled via 'blowing your nose' and the dirt particles are removed, never reaching your lower respiratory system (lungs). Without mucus (and boogers) you would have more dirt (and other particulates) in your lungs and be at higher risk of infection and other diseases.
