What is the role of hair and mucus in our noses?

Answer 1

Mucus is produced in the throat and brushed upwards by tiny hair-like structures called cilia. On its way up to the nose and mouth the mucus traps various dust, dirt and germs you breathe in. When the mucus reaches your mouth you either spit it out or swallow it, where it is dissolved in your stomach acid. If you did not produce mucus you would be more prone to respiratory infections, pepsin enjyme which release in our body do work only in the presence of HCL and mucus prevents the walls of stomach in contact with HCL etc. as the germs would be allowed easy access to your body.

The skin and mucous membranes from the body's first line of defense against disease. Most microscopic pathogens and microbes cannot pass through unbroken skin, although they can easily enter through cuts and other wounds. Mucus membranes protect internal organs that are continuous with the outside of the body.These membranes, which line the respiratory, digestive,urinary and the reproductive tracts, secrete a sticky fluid called mucus,which traps microbes.The mucus may then be expelled from the body, perhaps in a cough or sneeze or in feces.If the mucus are swallowed, digestive juices kill the microbes.

Mucus is a protective layer for internal soft organs/tissues.

In HUMANS, mucus acts as an important unspecific form of defense against pathogens preventing them from entering your body and coating our stomach walls which prevents the highly acidic acids in our stomach from digesting itself.

In ANIMALS, mucus has many roles.

1. defense against predators Ex. hagfish
2. motion Ex. snails
3. homes Ex. cave swiftlet
4. hunting Ex. New Zealand glowworm
5. bungee (escape) cord Ex. banana slug

Mucus is used to keep foreign substances from getting into your body; in your nose it is used to keep the nasal passage clear of these substances and prevents things such as dust mites, insects, pet dander, etc. from infiltrating your lungs.

Mucus is used to make a bigger loogie.

It traps dirt and germs to prevent your body from becoming infected from disease- causing microbes. It is part of the natural defence system.

The purpose of mucus, also loving termed phlegm or boogers, is to fortify the body from disease.

it stops dust from going into the body

It traps pathogens>>>novanet

Answer 3

Mucus is part of the filtration system that captures and removes small airborne particles (e.g. dust, pollen, spores) from the inhaled air. It is both sticky and fluid. Cilia on the cells lining the respiratory passages sweep up the dirty mucus, transporting it to the esophagus where it can either be swallowed or coughed out. This prevents these small airborne particles from collecting in the narrow passages in the lungs, where they might clog the passages or cause damage.

Answer 4

Trap incoming bacteria and other foreign debris.

Answer 5

Filtering out and trapping particles in the air.
