mucous membrane
lines nasal cavity to trap debris, contains cilia to brush debris to be destroyed; also for warming/moistening air
Mucous membranes refer to a type of tissue lining various organs and body cavities that secrete mucus. Mucus acts as a protective barrier, lubricant, and trap for foreign particles. Mucous membranes can be found in various body parts, such as the respiratory system, digestive system, and reproductive system.
The mucous membrane’s main function is to constantly produce mucus to keep surfaces moist and prevent them from drying out. Additionally, mucus helps to trap pathogens such as bacteria and viruses that may enter the body, preventing them from spreading or causing infection.
Examples of mucous membranes include the lining of the nasal cavity and sinuses, where they help to trap and remove airborne particles and microorganisms, and the lining of the digestive system, where they secrete mucus to help lubricate and protect the gut lining from digestive acids and enzymes.
Conditions such as dehydration, infections, allergies, and irritations can cause overproduction or underproduction of mucus, leading to various symptoms and complications. It is essential to maintain proper hydration and seek medical attention if unusual symptoms are present.
