module menu icon The structure of the lungs

Did you know?

  • The left lung is smaller than the right. Why? So there is space for the heart!
  • An adult has around 300 million alveoli in their lungs. If flattened out, these would cover an area roughly the size of a tennis court
  • The number of breaths someone takes in 24 hours is around 25,000
  • The lungs are incredibly delicate, which is why they are so easily damaged by breathing in things like tobacco smoke, pollution and dust. Reducing exposure to all of these things plays a crucial role in keeping the respiratory system healthy.
