Did you Know? List of Interesting Facts about the Respiratory System
Facts are statements which are held to be true and often contrasted with opinions and beliefs. Our unusual and interesting facts about the Respiratory System, trivia and information, including some useful statistics will fascinate everyone from kids and children to adults.

Interesting Facts about the Respiratory System are as follows:

  • 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

  • Fact 2 - The organs that are involved in breathing include the nose, throat, larynx, trachea, bronchi and lungs. Also called respiratory tract.
  • Respiratory System Fact 3 - The organs that are involved in breathing are referred to as the respiratory tract
  • 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
  • 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
  • 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 lungs
  • 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
    • 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
  • 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 speak
  • Respiratory System Fact 9 - The nose is the organ of smell and entrance to the respiratory tract
  • 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
  • Fact 11 - The respiratory system is susceptible to a number of diseases
  • Fact 12 - The lungs are prone to a wide range of disorders caused by pollutants in the air
  • Respiratory System Fact 13 - More than 20 million people in the United States have asthma
  • Fact 14 - Bronchiolitis is an inflammation of the bronchioles
  • 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
  • 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
  • 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
  • Respiratory System Fact 18 - Cystic fibrosis is an inherited disease affecting the lungs in the respiratory system
  • Fact 19 - Lung cancer is due to an abnormal growth of cells in the lungs and most often caused by smoking
  • Respiratory System Fact 20 - Pneumonia is the inflammation of the lungs usually occurs because of bacterial or viral infection of the respiratory system
