Respiratory Diseases And Disorders

Respiratory diseases pose significant health risks, particularly due to smoking. Men face a 23 times higher risk of lung cancer, while women have an 11 times higher risk. Other serious conditions include chronic bronchitis, emphysema, and heart disease, which are aggravated by smoking and pollutants. Common illnesses like the cold and influenza can affect the upper respiratory system, leading to complications. Pneumonia, bronchitis, and asthma are prevalent, often requiring medical treatment. Awareness of these issues is crucial for prevention and management.

  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
