Anonymous users2024-02-05Nasal discharge is not phlegm. The two are not the same thing.
1) Nasal mucus is a normal condition in which the nasal mucosa of some organisms secretes mucus all the time to moisten the nasal membrane, moisten the inhaled air, and stick to the dust, fine dust and microorganisms inhaled from the air.
Most nasal discharge is secreted by the nasal mucosa itself. The nasal mucosa contains a type of goblet cell that produces a lot of mucin, which is released into the outer cell and absorbs a large amount of water, forming nasal mucus for nasal use.
Part of the snot is actually tears. These tears are produced from the lacrimal glands, partially to the lacrimal ducts, and then through the nasolacrimal ducts to the nasal cavity, where they become part of the nasal discharge.
b) Phlegm is a substance made up of many components. Its high fluid content is the result of the transport of ions and water by the epithelium, while its macromolecules are mainly the products of blood leakage or local secretion of cells.

Anonymous users2024-01-30No.. Even if the snot can be spit out of the mouth, it is still snot.
Phlegm is a secretion of the respiratory tract. Under normal circumstances, the human respiratory tract secretes a small amount of mucus, which can moisten and warm the air inhaled into the lungs, and can also absorb some dust and harmful substances in the air.
When there is a lesion in the lungs, mucus is secreted abnormally, forming phlegm that we can feel.
Therefore, swallowing this mucus is harmful to the body.
