  • Respiratory Diseases
  • Diseases that influence the mechanics of breathing
    • Asthma
      • The bronchioles constrict
      • Flow of air reduced
      • Respiratory muscles must work harder
    • Emphysema
      • Lungs become stiff with fibers and are less elastic
      • Respiratory muscles must work harder
    • Bronchitis
      • Airways become inflamed and narrower
      • This restricts the flow of air
      • Respiratory muscles must work harder
    • Pneumothorax
      • Air in chest cavity equalizes pressure with outside air
      • Lungs collapse
      • Usually caused by trauma or injury
    • Apnea
      • Breathing slows or stops
      • Usually caused by problems in the respiratory centers of the brain
  • Diseases that minimize or prevent gas exchange
    • Pulmonary edema
      • Fluid between the alveolus and pulmonary capillary builds up
      • Increases distance that gases must exchange and slows down exchange
    • Smoke inhalation
      • Smoke particles coat the alveoli
      • Prevent the exchange of gases
    • Carbon monoxide poisoning
      • Carbon monoxide binds to hemoglobin tighter than oxygen or carbon dioxide
      • Minimizes delivery of oxygen to all tissues of body
      • Fatal if not caught soon
    • Chronic Obstructive Pulmonary Disease
      • Family of diseases that leads to reduction in airflow through respiratory system
