Mucus is produced by mucous membranes found throughout the body, primarily in the respiratory system.
These mucous membranes line various parts of the body, from the nose to the lungs, and are responsible for secreting mucus. The production increases, particularly in the nose or lower airways, in response to inflammation or irritation. This response aims to protect the respiratory system.
Where is Mucus Produced?
Mucus is primarily produced in:
- Nose: Nasal passages are lined with mucous membranes that trap dust, pollen, and other particles.
- Lower Airways (Lungs): The trachea, bronchi, and bronchioles are lined with cells that produce mucus.
- Other Areas: Mucous membranes are also found in other parts of the body such as the digestive system and genitourinary system, where they serve protective and lubricating functions.
Why is Mucus Produced?
The primary purpose of mucus production is to:
- Lubricate: Keeps tissues moist and prevents friction.
- Filter: Traps foreign particles like dust, bacteria, and viruses.
- Protect: Contains antibodies and enzymes that fight infection.
Increased Mucus Production
Inflammation, infections, allergies, and irritants can all trigger increased mucus production. When excess mucus is coughed up, it is often referred to as phlegm.
