Mucus is a normal protective layering around the airway, eye, nasal turbinate, and urogenital tract. Mucus is an adhesive viscoelastic gel produced in the airway by submucosal glands and goblet cells and is principally water. It also contains high-molecular weight mucous glycoproteins that form linear polymers.
This explains why coughing often occurs in those who smoke cigarettes. The body's natural reaction is to increase mucus production. In addition, mucus aids in moisturizing the inhaled air and prevents tissues such as the nasal and airway epithelia from drying out. [11] Mucus is produced continuously in the respiratory tract. Mucociliary action ...

[1] [2] [3] Droplet sizes range from < 1 μm to 1000 μm, [1] [2] and in typical breath there are around 100 droplets per litre of breath. So ...
Over 90% of adults pick their noses, and many people end up eating those boogers.. But it turns out snacking on snot is a bad idea. Boogers trap invading viruses and bacteria before they can enter ...
Mucophagy comes with some health risks due to the potential physical aggravation resulting from the action of nose picking, and the germs on fingers and in mucus. [1] Picking one's nose can cause upper airway irritation as well as other injuries including nasal septal perforation (a "through-and-through defect" of the cartilage separating the ...
