Workers in industries involving grinding or stone-breaking are exposed over years to excessive dust in their workplace. What kind of respiratory damage does chronic exposure of this sort typically cause, and what is this category of disorders called? (A) The dust particles are trapped entirely by nasal hair and mucus, so no lasting lung damage occurs even after years of exposure (B) The dust causes reversible bronchoconstriction that resolves fully within hours of leaving the workplace, similar to asthma (C) Chronic inhalation of fine dust particles causes inflammation leading to fibrosis of the lungs, reducing their functioning; such conditions are called occupational respiratory disorders (D) The dust particles are absorbed into the blood through the alveoli and cause damage mainly to the liver rather than the lungs Show answer and explanation ← Question 9 All Breathing and Exchange of Gases questions More NEET Biology chapters © 2026 Lumi (Aikolumi Software Pvt Ltd).
