COPD (Chronic Obstructive Pulmonary Disease)
COPD or chronic obstructive pulmonary disease is a lung condition caused by smoking tobacco, exposure to secondhand smoke, and/or air pollutants. Conditions that accompany COPD include:
- Chronic bronchitis
- Chronic cough
Symptoms of COPD include:
- Shortness of breath
- Chronic cough
Treatment of COPD include smoking cessation, medications, and surgery. The life expectancy of a person with COPD depends on the stage of the disease.
Lungs Design And PurposeThe lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
