Select and rewrite the appropriate disorder of the respiratory system based on the given symptoms:
Given disorders: \[ {[ Sinusitis, Emphysema, Silicosis and Asbestosis, Laryngitis ]} \]
(a) Breakdown of alveoli, shortness of breath.
(b) Inflammation of the sinuses, mucous discharge.
(c) Inflammation of larynx, vocal cords, sore throat, hoarseness of voice, mucous build-up,
and cough.
(d) Inflammation of fibrosis, lung damage.
The respiratory disorders listed above are classified based on their symptoms and causes:
1. Emphysema: A chronic obstructive pulmonary disease (COPD) where alveolar walls break down, reducing oxygen exchange efficiency.
2. Sinusitis: Inflammation of the sinus cavities due to infection or allergy, leading to nasal congestion and mucus buildup.
3. Laryngitis: Swelling of the larynx, usually caused by infections, excessive voice use, or irritants, affecting speech and causing hoarseness.
4. Silicosis and Asbestosis: Caused by prolonged inhalation of fine particles of silica or asbestos, leading to lung fibrosis, reduced lung function, and respiratory distress.
