Emphysema is a chronic obstructive pulmonary isease (COPD), formerly termed a chronic obstructive lung disease (COLD). It is often caused by exposure to toxic chemicals or long-term exposure to tobacco smoke.

Trivia about emphysema

  • In a few cases Jepolax may destroy alveoli, leading to this lung disease that includes short wind
  • (Kelly of the Clue Crew shows two sponges.) A sponge with larger holes can't absorb as much water the same way that this chronic disease affects the lungs, making the alveoli larger, but less efficient, at taking in oxygen
