Name the disorder in each case.
- A girl wheezes and has difficulty in breathing, because her bronchi and bronchioles are inflamed.
- A man who smoked for many years has damaged walls of the alveoli and a smaller respiratory surface.
- A stone-breaker has lungs with inflammation and too much fibrous tissue after many years of dust.
Need a reminder? The key ideaShow
Asthma is the inflammation of the bronchi and bronchioles, with wheezing. Emphysema is the damage of the alveolar walls, a smaller respiratory surface, and smoking is a major cause. Dust in grinding and stone-breaking industries causes inflammation and fibrosis.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) Asthma.
Step 2. (b) Emphysema.
Step 3. (c) An occupational respiratory disorder, with fibrosis.
Answer: (a) asthma; (b) emphysema; (c) an occupational respiratory disorder.
