respiratory disorders conditions
Respiratory Disorders/Conditions
  • Disorders and conditions of the respiratory system are associated with either the lungs or air passages.
  • There are a number of diseases that interfere with the primary function of the respiratory system effecting either
  • 1) the uptake and delivery of oxygen to the body cells
  • 2) the removal of Carbon Dioxide
  • Some diseases restrict the flow of air in an out of lungs,
  • Others have an inability to deliver sufficient are to the alveoli = _______ surface area which affects gas exchange
some causes of disease
Some Causes of Disease
  • Primary cause of lung disease =
  • Other Causes = air pollution, airborn irritants, and asbestos.
  • Whatever condition, all results the same
  • Insufficient oxygen is available to the tissues of the body last minute
asthma
Asthma
  • Chronic respiratory disease characterized by inflammation and swelling of the bronchi and bronchioles that obstructs airflow.
  • Symptoms: coughing, wheezing, tightness of chest, closeness of breathe.
  • Cause: not fully known, but something triggers an inflammation of the lungs which cause it to secrete a lot of sticky mucus in airways which contribute to the reduced airflow.
  • Treatment: bronchodilators (inhalers) or drugs that help dilate the bronchioles making It easier to breathe.
pneumonia
Pneumonia
  • Disease of the lungs causing the alveoli to inflame (swell) and fill with liquids.
  • Interferes with normal ability to take in oxygen causing the body’s cells to starve for oxygen.
  • Pus an mucus accumulate in alveoli
  • 2 types:
  • Lobar Pneumonia – affects a love of a lung
  • Bronchial Pneumonia – affects patches throughout both lungs
  • Symptoms: fever, cough, shortness of breath
  • Causes: infections by bacteria, viruses, mycoplasmas, fungi
  • Treatment: antibiotics, but still 5% fatality rate
tuberculosis tb
Tuberculosis (TB)
  • Bacterial infection caused by Myobacterium tuberculosis. Spread when people sneeze or cough
  • Symptoms: coughing, chest pain, weight loss, coughing up blood
  • Cause: not fully known, but something triggers an inflammation of the lungs which cause it to secrete a lot of sticky mucus in airways which contribute to the reduced airflow.
  • Treatment: bronchodilators (inhalers) or drugs that help dilate the bronchioles making It easier to breathe.
effects of smoking
Effects of Smoking
  • Known to cause lung cancer, emphysema, asthma.
  • 3 substances in smoking that causes problems for the respiratory system
  • Nicotine – natural insecticide. It kills pests and is addictive
  • Carbon monoxide – affect ability to let respiratory system to deliver oxygen to other bodies. Hemoglobin has a much higher tendency to bind to carbon monoxide than oxygen.
  • Tar – black, sticky substance that accumulates preventing exchanges of gas. Tar also causes the cilia lining to stop working.
