Smoking and the Respiratory System l Smoking is associated with 2 chronic obstructive pulmonary diseases: • 1. Chronic Bronchitis • 2. Pulmonary Emphysema

Chronic Bronchitis Occurs when the bronchi are irritated because the cilia have become useless due to a build up of tar. l This situation causes chronic coughing and excessive mucous secretion of the bronchial tree. l

Pulmonary Emphysema Caused by the destruction of the tiny oxygen absorbing sacs in the lungs. l This situation makes it very difficult to BREATH! l
