Answer
Smokers are more likely to suffer from respiratory tract infections due to impaired mucociliary clearance, compromised immune response, and changes in the respiratory microbiota.
Solution
a
Impaired mucociliary clearance: Smoking damages the cilia in the respiratory tract, reducing their ability to clear pathogens
b
Compromised immune response: Smoking can suppress the immune system, making it less effective at fighting off infections
c
Changes in respiratory microbiota: Smoking can alter the normal microbiota, potentially increasing the proportion of pathogenic bacteria
Key Concept
Increased susceptibility to infections in smokers
Explanation
Smoking damages the respiratory system's natural defenses, leading to a higher risk of infection.
