Interesting Facts about the Respiratory System

  1. Fact 1 - Definition: The system for
    taking in oxygen and giving off carbon dioxide accomplished
    by breathing. The group of organs responsible for carrying
    oxygen from the air to the bloodstream and for expelling
    carbon dioxide

  2. Fact 2 - The organs that are involved
    in breathing include the nose, throat, larynx, trachea,
    bronchi and lungs. Also called respiratory tract.

  3. Respiratory System Fact 3 - The
    organs that are involved in breathing are referred to as the
    respiratory tract

  4. Fact 4 - The lungs are the main
    organs of the respiratory system in which oxygen is taken
    into the body and carbon dioxide is breathed out

  5. Respiratory System Fact 5 - The
    respiratory system and red blood cells: Red blood cells are
    responsible for picking up the oxygen in the lungs and carry
    oxygen to the body cells. The red blood cells then collect
    the carbon dioxide (waste gas product) produced by our cells
    and transport the carbon dioxide back to the lungs which we
    breathe out when we exhale

  6. Fact 6 - The trachea: The trachea is
    also referred to as the windpipe. The trachea, or windpipe,
    filters the air we breathe and branches into the bronchi

        -- The trachea is also lined with
    cilia, which clears fluids and particles out of the
    airway so that they stay out of the lungs

        -- The trachea divides into left and
    right air tubes called bronchi, which connect to the

  7. Fact 7 - The bronchi: The bronchi are
    two air tubes that branch off of the trachea and carry air
    directly into the lungs

        -- Smaller tubes are called

        -- Bronchioles end in tiny air sacs
    called alveoli

        -- The exchange of oxygen and carbon
    dioxide takes place in the air sacs (alveoli)

        -- Each lung has about 300-400
    million alveoli

  8. Fact 8 - larynx is a cartilaginous
    structure at the top of the trachea which contains elastic
    vocal cords that are the source of the vocal tone when we

  9. Respiratory System Fact 9 - The nose
    is the organ of smell and entrance to the respiratory tract

  10. Fact 10 - Air can also be taken in
    through the mouth. The epiglottis, a small flap of tissue,
    covers the air-only passage when we swallow keeping food and
    liquid from going into the lungs

  11. Fact 11 - The respiratory system is
    susceptible to a number of diseases

  12. Fact 12 - The lungs are prone to a
    wide range of disorders caused by pollutants in the air

  13. Respiratory System Fact 13 - More
    than 20 million people in the United States have asthma

  14. Fact 14 - Bronchiolitis is an
    inflammation of the bronchioles

  15. Respiratory System Fact 15 -
    Emphysema is most often caused by smoking.  In emphysema the
    alveoli become damaged making it difficult to breathe and
    get enough oxygen into the blood

  16. Fact 16 - Bronchitis occurs when the
    membranes lining the larger bronchial tubes become inflamed
    and an excessive amount of mucus is produced resulting in a
    bad cough and painful breathing

  17. Fact 17 - The common cold is the most
    common respiratory infection

        -- The common cold is caused by 200
    different viruses

        -- The viruses cause inflammation in
    the upper respiratory tract

  18. Respiratory System Fact 18 - Cystic
    fibrosis is an inherited disease affecting the lungs in the
    respiratory system

  19. Fact 19 - Lung cancer is due to an
    abnormal growth of cells in the lungs and most often caused
    by smoking

  20. Respiratory System Fact 20 -
    Pneumonia is the inflammation of the lungs usually occurs
    because of bacterial or viral infection of the respiratory
