it somehow prevents foreign materials to get through the body.
the answer is mucus
Mucus serves several important functions in the body. It acts as a protective barrier, trapping pathogens, dust, and other particles to prevent them from entering the respiratory and digestive tracts. Additionally, mucus keeps tissues moist, aiding in the smooth passage of food and the movement of air in the lungs. It also contains antibodies and enzymes that help neutralize harmful microorganisms.
the function of the mucus blanket in the lungs is to filter and moisten the air.
Mucus protects stomach lining from gastric acids.
Since they are guard dogs, and very protective.
Mucus secreted by goblet cells trap the foreign particles. Cilia push the particles out wards. This protects your lungs from damage by the foreign particles.
The stomach has a lining of protective mucus.
The function is to get rid of excess mucus.
Mucus serves several important functions in the body, primarily as a protective barrier. It traps dust, pathogens, and other foreign particles, preventing them from entering the respiratory and digestive systems. Additionally, mucus keeps tissues moist, which is essential for proper function and healing. It also plays a role in the immune response by containing antimicrobial properties and antibodies.
The mucus protects the inner lining of the stomach from the action of acids.
Mucus in the respiratory system serves as a protective barrier, trapping dust, pathogens, and other particles. Cilia, tiny hair-like structures lining the airways, help move mucus upward toward the throat, where it can be swallowed or expelled. The epithelial cells in the respiratory tract also produce mucus to keep the airways moist and prevent infection. Proper function of these mechanisms is essential to keep mucus from reaching the lungs and causing respiratory issues.
Mucus in the lungs serves as a protective barrier, trapping dust, pathogens, and other particles to prevent them from entering the bloodstream. It is produced by goblet cells and the airway epithelium and is moved by cilia lining the respiratory tract. In certain conditions, such as infections or chronic diseases, mucus production can increase, or ciliary function can be impaired, causing mucus to accumulate and stay trapped in the lungs. Additionally, dehydration or thickened mucus can hinder its clearance, leading to further retention.
