🫁 Destruction of Alveolar Walls

Let’s understand this step by step in a very simple way.

First, what are alveoli?
Alveoli are tiny air sacs in the lungs.

👉 Think of them like small balloons where oxygen enters the blood and carbon dioxide goes out.

What is the alveolar wall?
Each alveolus has a very thin wall that helps in gas exchange.

👉 This thin wall is very important for breathing.

What happens if these walls are destroyed?
If alveolar walls are damaged:

• Air sacs lose their shape
• They become larger and less effective
• Gas exchange becomes poor

👉 This leads to breathing difficulty.

What is this condition called?

✅ Correct Answer: (c) Emphysema

What is emphysema?
It is a lung disease where alveolar walls are destroyed, leading to reduced oxygen exchange.

👉 Common in smokers and COPD patients.

Why other options are not correct?

• (a) Empyema → ❌ Collection of pus in pleural cavity
• (b) Bronchitis → ❌ Inflammation of bronchi (airways), not alveoli
• (d) Lung abscess → ❌ Localized pus-filled cavity in lung tissue

Simple Exam Trick:
Alveoli destroyed → Air sacs damaged → Emphysema

📌 Note: Emphysema is a type of COPD and causes progressive breathlessness.
