Glossary

Lungs: The two organs of respiration that bring air and blood into close contact so that oxygen can be added to and carbon dioxide removed from the blood.

Bronchitis: Inflammation(swelling and reddening) of the bronchi.

Pneumonia: An inflammatory infection that occurs in the lung.

Obstructive lung disease: A condition in which there is a persistent disruption of air flow into and out of the lungs.

Pulmonary Emphysema: Pulmonary emphysema is a disorder affecting the alveoli (tiny air sacs) of the lungs. The transfer of oxygen and carbon dioxide in the lungs takes place in the walls of the alveoli. In emphysema, the alveoli become abnormally inflated, damaging their walls and making it harder to breathe. People who smoke or have chronic bronchitis have an increased risk of emphysema.

Bronchodilators: Drugs that relax the muscles around the airways and help in opening up the airways.

Pulmonary function tests: Tests used to measure the ability of the lungs to exchange air.
