what is the purpose of mucus?

Answer 1

In the respiratory system, it catches unknown matter and tries to prevent it from entering the body, especially in the nose. Mucus aids in the protection of the lungs by trapping foreign particles that enter the nose during normal breathing. Additionally, it prevents tissues from drying out.

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 must be cleared by blowing the nose or expectorating phlegm from the throat. Among the components of nasal mucus are tears.

Dried nasal mucus (vulgarly or colloquially called "snot", "booger(s)" (US) or "bogey" (UK)) is partially solidified mucus from the nose. Dried nasal mucus forms when the mucus traps dust and other particles in the air. Mucus dries around the particle and hardens, somewhat like a pearl forming in an oyster. Since catching foreign particles is one of the main functions of nasal mucus, the presence of dried nasal mucus is a good indicator of a properly functioning nose.

In the digestive system, mucus is used as a lubricant for materials which must pass over membranes, e.g., food passing down the esophagus. A layer of mucus along the inner walls of the stomach is vital to protect the cell linings of that organ from the highly acidic environment within it.

In the reproductive system, cervical mucus prevents infection and helps the movement of the penis during sexual intercourse. When thin, cervical mucus helps the movement of spermatozoa.

Generally mucus is clear and thin, serving to filter air during inhalation. During times of infection, mucus can change color to yellow or green either as a result of trapped bacteria, or due to the body's reaction to viral infection.

In the case of bacterial infection, the bacterium become trapped in already clogged sinuses, breeding in the moist, nutrient-rich environment. In this case, the clogged sinuses are a result of some other condition (such as allergies) and the bacterial infection is secondary to this original cause. When two different color of common bacteria become mixed (such as yellow Staphylococcus aureus and blue Pseudomonas pyocyanea) the resulting shade is often green. Antibiotics may be used fruitfully to treat the secondary infection in these cases, but will generally not help with the original cause.

In the case of a viral infection such as cold or flu, the first stage of infection causes the production of a clear, thin mucus in the nose or back of the throat. As the body begins to react to the virus (generally one to three days), mucus thickens and may turn yellow or green. In these cases, antibiotics will not be useful, and are a major source of misuse. Treatment is generally symptom-based; the only cure is to allow the immune system to fight off the virus over time.

Like your questions. I will try to explain it as simple as I can, but can't promise you nothing. The trachea, or windpipe, is the bony tube that connects the nose and mouth to the lungs, and is an important part of the vertebrate respiratory system. When an individual breathes in, air flows into the lungs for respiration through the windpipe. Because of its primary function, any damage incurred to the trachea is potentially life-threatening. The bony skeletal trachea is comprised of cartilage and ligaments, and is located at the front of the neck. The trachea begins at the lower part of the larynx and continues to the lungs, where it branches into the right and left bronchi. It measures 3.9 to 4.7 inches (10-12 cm) in length, and .62 to .7 inches (16-18 mm) in diameter. The trachea is composed of 16 to 20 “c” shaped rings of cartilage connected by ligaments, with a ciliated-lined mucus membrane. It is this structure that helps push objects out of the airway should something become lodged. Because it is connected to the same tubing system that allows an individual to swallow, the respiratory system has evolved a mechanism to prevent choking and respiratory failures. When an object blocks the trachea, choking occurs. The coughing reflex allows the ciliated cells to push the object out of the trachea and out of the respiratory system. Inflammation of the trachea can lead to other conditions, such as tracheitis, which is the inflammation of the linings of the trachea. Tracheobronchitis occurs when the mucous membrane of the trachea and bronchi become swollen. As for what's the purpose of Cilia, well lets start with the definition. Cilia is Latin for "eyelash." These tiny protuberances on single-cells organisms wave-like hairs to move the cell around or something around the cell. They are responsible for protecting us from germs in our lungs and pushing an ovum down the fallopian tube. Flagella are longer such hairs, usually found in ones or twos, such as the "tail" of a sperm. Eukaryotes, single-celled organisms, use cilia and flagella to move are also found in ferns, algae, bacteria, and inside many animals. This adaptation originally allowed independent cellular creatures, like Paramecium, to move around in search of food, rather than wait until food came to it. Since then, cells as part of larger systems continue to use cilia to great advantage.

Answer 5

Tiny hair like cillia in your nasal and airway passages and sticky mucus help to trap particules of dust, debris, and germs before they enter into your body and make you sick.

Then you expel the mucus.

Answer 6

There is no purpose for it. It's not like your body uses the mucus for anything. It's the result of something. Your body produces it. Why, I don't know. I'm sure you'll find out from someone soon.

Answer 7

- it lubricates and moitens linings of cavities (e.g. oesophagus)
- it acts as a 1st line defense mechanism - removing bugs and dust particles as that in the lung, nasal ... (hairs and cilia helps removing them + coughing)
- it protects layers of the body - e.g. prevent stomach from digesting itself. In fact that's how peptic ulcer starts
- it serves some purposes in other body parts i.e. may make environment unfavourable for sperm in the vagina - the basis of some contraceptive mechanism

Answer 8

Either lubrication or protection. If you have allergies, your body is freaking out about something in the environment and is using mucous to try to flush the foreign body out of your system.

Answer 9

what is a function of mucus? it traps phathogens (gradpoint)

Answer 10

its a viscous fld. secreted by the mucous membrane. it acts as a

protective barrier over the membranes
a lubricant
& an enzyme carrier
