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.

What is the purpose of the mucous membrane?
The mucous membrane serves to protect and lubricate various cavities in the body, such as the respiratory, digestive, and reproductive tracts. It also plays a role in immune defense by trapping pathogens and preventing them from entering the body.
Can you get drunk via a mucous membrane?
line and protect the inside of your body
The lining of the mouth is an example of what membrane?
The lining of the mouth is an example of a mucous membrane. Mucous membranes line various cavities in the body and produce mucus to protect and lubricate the underlying tissues.
Are nipples considered a mucous membrane?
No, nipples are not considered mucous membranes. Mucous membranes line various body cavities and organs that are exposed to the external environment, such as the mouth, nose, and digestive tract, and secrete mucus to protect against infection. Nipples are composed of skin, glandular tissue, muscle, and connective tissue, but do not secrete mucus.
What is hyperemia of mucous membrane?
Hyperemia of the mucous membrane refers to an increased blood flow to the mucous lining of a specific area in the body. This can result in redness, swelling, and irritation of the mucous membrane due to increased blood supply. Hyperemia can be caused by various factors such as inflammation, infection, or irritation.
Which body system would NOT be lined with a mucous membrane?
The skeletal system would not be lined with a mucous membrane. Mucous membranes are found in the respiratory, digestive, urinary, and reproductive systems to secrete mucus that helps protect and lubricate these cavities.
Do mucous membrane prevent infection?
Yes, mucous membranes help prevent infection by acting as a physical barrier that traps pathogens and prevents them from entering the body. Additionally, mucous membranes produce mucus that contains enzymes and antibodies to help neutralize and eliminate pathogens.
Mucous is the substance secreted by the mucous membranes?
Yes, that's correct. Mucus is a slippery secretion produced by mucous membranes lining various body cavities and serves to protect and lubricate these surfaces.
What are the types of membranes lining cavities that communicate with the exterior of the body?
The types of membranes lining cavities that communicate with the exterior of the body are mucous membranes. These membranes are found in areas such as the respiratory, digestive, urinary, and reproductive tracts, and they secrete mucus to protect and lubricate the tissues.
Common locations of the Mucous Membrane?
Mucous membranes are found in the respiratory tract, digestive tract, urinary tract, and reproductive tract. They line cavities and canals that come into contact with the external environment and help protect these areas from infection.
What lines cavities that communicate with the exterior of the body?
Mucous Membrane
What does mucous mean?
it means your body is fighting off an infection
