Question

Give an account of the disorder of human respiratory system.

Answer 1

(Any two).

• Common Respiratory Disorders Include: Chronic Obstructive Pulmonary Disease(COPD) - Irritation of the lungs can lead to asthma, emphysema, and chronic bronchitis and people can develop two or three of these together.
• Chronic bronchitis -Any irritant reaching the bronchi and bronchioles will stimulate increased secretion of mucus. In chronic bronchitis, the air passages become clogged with mucus, and this leads to a persistent cough.
• Emphysema - The delicate walls of the alveoli break down, reducing the gas exchange area of the lungs. The condition develops slowly and is seldom a direct cause of death.
• Asthma - Periodic constriction of the bronchi and bronchioles makes it more difficult to breathe.
  
• Pneumonia - An infection of the alveoli. It can be caused by many kinds of both bacteria and viruses. Tissue fluids accumulate in the alveoli reducing the surface area exposed to air. If enough alveoli are affected, the patient may need supplemental oxygen.
