mucous membrane is a part of body defense just like our skin but it lines the inner surface of our body it protects the body against the acids production and pH changes in side our body since it is a thick layer it also act as shock absorber.
The mucous membrane prevents infection within the body by stopping invasion by antigens, micro organisms and foreign materials. These hazards can not cross the mucous membrane and instead die before causing infection.
This is so because when pathogenic or virulent organisms attack the physiological being of a human - the first obstruction they encounter is the skin and the mucus lining in the nose, ear etc. directly exposed organs. The skin prevents the organisms from entering into the tissue systems and acts more as a barrier than a counter - defense whereas the mucus traps pathogens and expels them when we sneeze. Hence, these two membranes are called the body's first line of defense.
Mucus is a slippery secretion produced by, and covering, mucous membranes. Mucous fluid is typically produced from cells found in mucous glands. Mucous cells secrete products that are rich in glycoproteins and water. Mucous fluid may also originate from mixed glands, which contain both serous and mucous cells. It is a viscous colloid containing antiseptic enzymes (such as lysozyme), immunoglobulins, inorganic salts, proteins such as lactoferrin, and glycoproteins known as mucins that are produced by goblet cells in the mucous membranes and submucosal glands.
In the human respiratory system, mucus aids in the protection of the lungs by trapping foreign particles that enter it, in particular, through the nose, during normal breathing. "Phlegm" is a specialized term for mucus that is restricted to the respiratory tract, whereas the term "nasal mucus" describes secretions of the nasal passages.
In general, nasal 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. The green color of mucus comes from the heme group in the iron-containing enzyme myeloperoxidase secreted by white blood cells as a cytotoxic defense during a respiratory burst.
The mucous is used to help trap pathogens, then we help get rid of the mucous and the pathogens by blowing our noses and/or coughing.

Mucous Membrane
The mucous membrane lines all body cavities that open to the exterior, such as those of hollow organs of the respiratory, digestive, urinary, and reproductive tracts.
it means your body is fighting off an infection
mucous membranes
Epithelium :)
The mucous membrane line all exterior openings to your body. Their main function is to protect your body from disease. That is mostly their only function except for being annoying.
Any body area that has an outlet to the out side is covered in a mucous membrane: respiratory tact. digestive tract, urinary tract, even the membrane that surrounds the orbit of the eye (eye ball).
A mucous membrane is a layer of epithelial tissue which lines an area of the body which comes into contact with air. Mucous membranes are moist because of the presence of glands which secrete a thick fluid known as mucus, and they are important for a number of bodily functions. Mucous membranes line the urogenital tract, digestive tract, and respiratory tract, with one of the more well known mucous membranes being the lining of the interior of the nose. The moisture found in a mucous membrane acts to protect the body by creating a barrier and preventing the inside of the body from drying out. Mucus also traps pathogens, dirt, and particulate matter so that they can be sequestered and eliminated by the body. The nose is particularly famous for this, using mucus as a barrier between many harmful substances and the respiratory tract. Some sections of mucous membrane also have small hairs known as cilia which act as traps, and can move to push things across the surface of the membrane.
Green mucous means your body is currently fighting an infection.
Mucous membranes do this by producing a fluid called mucous.
