Understanding your lungs and COPD

Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term for a group of conditions that cause an obstruction to the airflow in the lungs either by:

  • Damage to the air sacs (alveoli) and breathing tubes (bronchi and bronchioles).
  • Swelling and sputum/mucus production in the breathing tubes.
