How is snot created?

Answer 1

The internal portion of your nose is lined with something called a mucous membrane. This membrane is a thin layer of cells that produces mucus, a kind of slime. Mucus is mostly water and mucin, which is a kind of sugar.

In the nose, mucus has two roles. One is to moisten, lubricate, and protect the inside of the nasal passage. The other is to work as a kind of filter in combination with tiny hair-like projections called cilia. Cilia moistened by the mucus trap dust, bacteria, and other small particles breathed in with air along with head cells that come from the lining of he nose itself. This filter is very important to preventing all that junk from reaching the lungs.

If some bacteria make it past the defenses of the mucous membrane and you get a sinus infection snot also carries out the products of those bacteria and the cells killed off by them. This is why snot turns yellow.

Answer 2

Snot is produced by the mucus membranes in your nose and sinuses. These membranes secrete a combination of water, proteins, antibodies, and glycoproteins to trap and remove foreign particles, like dust and allergens, from the air you breathe. Excess mucus can then be expelled through your nose or down the back of your throat.

Answer 3

Snot or mucus is made up of water and the protein mucin. Mucus comes from specialized goblet cells which secrete the mucin into the airways. They absorb liquid and expand in volume when exposed to an irritants like viruses, pollen, or bacteria before they can get into the body. Mucus also coats the mouth, nose, sinuses, throat, lungs and gastrointestinal tract protecting the surfaces and keeping them moist.

Answer 4

When a little monster in your nose gets sick it makes nasty green slimmy stuff.

Answer 5

Snot is the buildup of mucus and other debris inhaled through the nose and mouth. It is generally collected in the nasal cavity and throat. Snot exits the body mainly through the nostrils.
