    increased debris in the airways
  • d)
    increased temperature in the lungs
Correct answer is option 'C'. Can you explain this answer?

The destruction of the cilia lining the respiratory tract would result...
The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. So, the destruction of cilia linning results in the increasing in deposition of debris in the airways.

The Role of Cilia in the Respiratory System
Cilia are tiny hair-like structures lining the respiratory tract, playing a crucial role in maintaining respiratory health. Their primary function is to move mucus and trapped particles out of the airways, thereby keeping the lungs clear of debris and pathogens.

Consequences of Cilia Destruction
When the cilia are destroyed, several detrimental effects occur:
  • Decreased Mucus Clearance: Cilia help in the movement of mucus. Without them, mucus accumulates, leading to blockages.
  • Increased Debris in the Airways: The correct answer, option 'C', indicates that with damaged cilia, debris, pathogens, and particulate matter remain in the airways. This accumulation can lead to infections and respiratory issues.
  • Increased Risk of Infection: The failure to clear mucus effectively can increase susceptibility to infections since pathogens can thrive in stagnant mucus.



Why Other Options are Incorrect
  • Decreased Breathing Rate: This is unlikely as the body typically compensates for airway obstruction by increasing the breathing rate.
  • Decreased Mucus Production: Cilia destruction does not directly affect mucus production; instead, it leads to mucus accumulation.
  • Increased Temperature in the Lungs: This is not a direct result of cilia destruction; lung temperature is regulated by internal mechanisms.



Conclusion
In summary, the destruction of cilia lining the respiratory tract primarily leads to increased debris in the airways, significantly impacting respiratory health and function.
