  1. Respiratory Diseases And Disorders

  2. 1. Smoking and Respiratory Problems • Lung cancer- 23 times higher risk for males and 11 times higher risk for females • Chronic Bronchitis and Emphysema- 5 times higher risk • Heart Disease- 2 times higher risk • secondhand smoke- inhaling smoke from others that are smoking, also unhealthy and can harm the respiratory system

  3. 2. Causes of Respiratory Problems • Smoking • Polluted air • Coal dust • asbestos 3. Common Cold • Caused by bacteria, viruses or other micro-organisms • usually affects upper respiratory system- from nose to pharynx • can cause irritation and swelling in larynx, trachea, and bronchi

  4. 4. Influenza the “flu” • Caused by a virus • can affect many body systems • virus multiplies in the cells of the alveoli and damages them 5. Pneumonia • Infection in the alveoli • can be caused by bacteria, viruses, or other micro-organisms • can be treated with antibiotics

  5. 6. Bronchitis • Bronchial tubes are irritated and swell, and too much mucus is produced • can be treated with antibiotics and clears up within a few weeks • person coughs a lot to clear mucus from airway, but damages cilia and bronchial tubes • scar tissue can form and the respiratory system cannot perform properly

  6. 7. Emphysema • Disease that causes alveoli in the lungs to enlarge • when cells in alveoli swell, they release an enzyme that causes walls of alveoli to break down • causes less oxygen in the bloodstream and shortness of breath • often develop heart problems because heart has to work harder to supply oxygen to body cells

  7. 8. Lung Cancer 9. Asthma • 3rd leading cause of death in U.S. • greatest cause is inhaling tar in cigarette smoke • carcinogens- substances that can cause uncontrolled growth of cells • Lung disorder that can cause shortness of breath, wheezing, or coughing • asthma attack- bronchial tubes contract quickly, medicines in inhalers relax the tubes • often an allergic reaction to a foreign substance • attacks can be caused by cigarette smoke, plant pollen, certain foods, or stress
