MEDIUM

Cigarette smoking is a major risk factor that leads to the chronic respiratory disorder known as Emphysema (वातस्फीति). What is the primary pathological mechanism of this disease?

Destruction of lung alveoli walls reducing the respiratory surface area

Proliferation of cancerous cells in the bronchial epithelium

Infection and inflammation of the pleural membrane surrounding the lungs

Accumulation of fibrous tissue in the pulmonary interstitium

Explanation

🌟 Quick Verification

Direct Answer: The correct answer is Destruction of lung alveoli walls reducing the respiratory surface area.
Core Concept: [Emphysema is a chronic obstructive pulmonary disease primarily caused by tobacco smoke.]

🧠 Solution Blueprint

Pathological Mechanism:
- Cigarette smoke introduces harmful toxins and particulate matter that trigger chronic inflammation in the lungs.
- This inflammation leads to the breakdown of elastin proteins in the alveolar walls, causing destruction of alveolar walls.
- Consequently, the respiratory surface area is severely diminished, leading to breathing difficulties and shortness of breath.

Administration of the BCG vaccine

Ensuring proper indoor ventilation and wearing masks

Explanation

🌟 Quick Verification

Direct Answer: The correct answer is Introducing Gambusia fish and oil spraying.
Core Concept: [Anti-larval measures for vector-borne disease control].

🧠 Solution Blueprint

Step-by-Step Solution:
- Vector-borne diseases like Malaria are controlled by targeting mosquito larvae in standing water.
- Introducing Gambusia fish into ponds consumes mosquito larvae naturally.
- Oil spraying creates a thin film on water surfaces, cutting off oxygen supply to mosquito larvae and suffocating them.
