SPUTUM
Sputum
phlegm
The lay person's term for that is phlegm.
Phlegm
respiratory tract "In the respiratory tree, a ciliated epithelium conveys foreign particles entrapped in mucus toward the pharynx either to be expelled or swallowed. This so-called ciliary "escalator" propels entrapped particles..."
mucus!!!!!!mucus trap the dirt in the trachea!
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.
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.
Digestive 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.
mucus
I think your thinking of applesauce. Sputum is actually found in llama spit.
It is collected in Mucus and expelled through coughing.
Once a fungus is inhaled, it will multiply, either in the upper or lower respiratory tracts. As the fungi multiply, it will interfere with breathing, causing an overabundance of mucus. An upper respiratory tract infection includes the common cold and laryngitis. Lower respiratory tract infections are usually more serious and include bronchitis and pneumonia, both of which can be fatal.
