How does mucous membrane protect the body from infection?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

prevents bacteria from entering the blood
