How our Lungs Work

Our lungs are amazing!

Did you know that:

  • Our lungs are about the size of a pair of footballs
  • The surface area of the lungs is roughly the same size as a tennis court
  • By the time a person reaches 70 years old, they will have taken at least 600 million breaths
  • The lungs are the largest organ in the body and the only internal organ exposed to the external environment

How our lungs work:

  • To breathe in we use our muscles (the muscles around our ribs and the diaphragm). The diaphragm tightens and flattens, allowing air to be sucked in to the lungs. To breathe out all of these muscles relax naturally letting the air out.
  • The air then passes through the throat into the trachea (the wind pipe).
  • The trachea then splits into two, the left and the right bronchial tubes. Like the branches of a tree the bronchial tube then splits again and again becoming narrower and narrower.
  • The smallest airways then end as the alveoli which are small thin air sacs clustered like bunches of grapes. These alveoli are surrounded by tiny blood vessels (capillaries).
  • Oxygen moves over the walls of the alveoli into the blood stream (it is picked up by the haemoglobin) and is carried around the rest of the body
  • At the same time carbon dioxide (waste gas) is returned through the alveoli into the lungs and is breathed out.
