Health Issues Related to the Human Respiratory System

8.4 Health Issues Related to The Human Respiratory System
 
A mind map focusing on Chronic Obstructive Pulmonary Disease with three branches: Emphysema: Alveoli lose elasticity and increase in size. Damaged alveoli walls reduce surface area, making gaseous exchange less efficient. Chronic Bronchitis: Bronchioles become inflamed, swollen, and clogged. This reduces airflow and makes breathing difficult. Asthma: Bronchiole walls become swollen and thickened. This condition makes breathing difficult and causes shortness of breath.
 
Chronic Obstructive Pulmonary Disease (COPD)
Emphysema
  • In emphysema, the alveolus loses its elasticity and increases in size.
  • The alveolus wall is damaged, the total surface area of alveolus decreases and the gaseous exchange becomes less efficient.
Chronic Bronchitis
  • In chronic bronchitis, the bronchiole becomes inflamed, swollen and blocked.
  • This reduces the flow of air and causes difficulties in breathing.
  • A large amount of mucus formed will cause continuous coughing.
  • Damaged cilium causes difficulty in expelling mucus.
Asthma
  • For an asthmatic patient, the bronchiole walls become swollen and thick.
  • The opening of the bronchiole tube becomes smaller and the air passage becomes narrower.
  • This condition leads to difficulties in breathing and causes breathlessness.
