explain why humans have nasal muscus.?

Answer 1

For the same reason that other mammals do...
To trap dust,debris,and insects before they can make their way to the lungs.Even in the fresh air of a rural setting there are many air-borne irritants that our bodies just don't like.....hence mucous.
Luckily for us humans (who have fingers) the stuff dries up,and turns into boogers that we can pick out at our convenience!

Answer 2

For a lot of reasons, actually. One of the most important, is to capture germs before entering the body through the nose. If germs do enter the body then the mucus attempts to expel it. That is why you get a runny nose when you are sick. It does capture dust spores and other irritants to the human lungs and sinuses.

Nasal mucus is mucus from the nose. Nasal mucus is produced by the nasal mucosa, and serves to protect the respiratory tract. Nasal mucus is produced continually, and most of it is swallowed unconsciously.

Snot is a commonly used colloquial term used to refer to nasal mucus. Increased mucus production in the respiratory tract is a symptom of many common diseases, such as the common cold. The presence of mucus in the nose and throat is normal, but increased quantities can impede comfortable breathing and may be cleared by blowing the nose or expectorating excess mucus from the back of the throat. Nasal mucus may also be removed by using traditional methods of nasal irrigation. In Western societies, it is more common to treat excess mucus with drugs such as decongestants.

A booger or bogie is better known as a rhinolith in medical terminology (from the Greek rhino meaning nose, and lithos meaning stone). Rhinoliths form when the mucus traps dust and other particles in the air. Mucus dries around the particle and hardens into a solid or semi-solid sticky object, resulting in the particle's eventual expulsion from the body. Since catching foreign particles is one of the main functions of nasal mucus, the presence of rhinoliths is a good indicator of a properly functioning nose (as opposed to a "runny nose", which can indicate illness).

Bogey Ball is an infamous artwork by James R Ford. For this long term project Ford was constantly collecting his bogies in an eggcup and making them into a ball, in an attempt to create an egg-sized mucus mass. Picking and collecting bogies on a daily basis, and adding them to the ball periodically, was an obsessive and frustrating process, demanding a lot of commitment on Ford's part. Bogies are essentially comprised of dust and skin cells, and so Bogey Ball is actually a physical record of all the different places Ford has been and people he's met.

A loogie is a slang expression used in North America to refer to a mass of phlegm and saliva that is ejected from the mouth after being extracted from the throat of a person with nasal congestion. The expression "hocking a loogie" refers to extracting the phlegm in an obviously noisy manner involving violent vibrations of the glottis, producing a low, guttural, rumbling sound. This practice may have other names in other countries and within the medical community. In the UK, the mass can be referred to as a 'flob', a portmanteau of the phonetic pronounciation of phlegm and 'gob', a slang term for saliva.

A "snot rocket" is a slang term referencing the act of holding one nostril while forcefully exhaling through the other mucous filled nostril resulting in a "rocket"-like projection of phlegm. Common during allergy season and during winter cold and flu season. If you practice enough, snot rockets can be an effective weapon.

Dried nasal mucus is often removed by nose-picking, a common activity which is socially taboo in most cultures. The social taboos regarding nasal mucus have also led to a wide variety of slang terms for nasal mucus and rhinoliths, including "snot" for nasal mucus, and "boogers" (US) or "bogies" (UK) for rhinoliths.

They have mucus to keep the dust and anything that is not suppose to be in your nose out. You sneeze so you can get the stuff out of your nose once there is too much mucus or stuff. I think the mucus can also help in your stomach since the acids in your stomach are very acidic and the mucus kinds of protects you stomach when it lets acid go.

It traps gunk, dirt, bacteria, virii, little bugs, soot, dust, and other particles that are entering your body. This keeps most of the worst stuff out of our lungs, and is therefore very useful.
