                                                    Human Lungs

If I ask you, what is the most important thing to live as a human then most probably your answer would be ‘breathing’. Have you ever wondered which human organ is responsible for the core job of processing oxygen for breathing? The answer is lungs. In human body, there are two lungs, right lung and left lung. Both the lungs together weight 2.9 pounds. Your left lung is slightly lighter than the right one.

Quick Facts: –

  • Left lung is smaller in comparison to the right lung as it has two lobes and the right lung has three lobes.
  • Your lungs expand when you breathe in. Their expansion is possible only because the diaphragm squeezes.
  • There are approximately 300 to 500 million tiny and spongy air sacks that are no thicker than a cell. These air sacks are known as alveoli.
  • These alveoli are surrounded by the smallest blood vessels in the human body called capillaries.
  • In an adult human, the total internal surface area of lungs is 50-70 square metres.
  • Your lungs are located in your chest behind your rib cage.
  • There are various diseases that affect your lungs like: – pneumonia, emphysema, bronchitis and tuberculosis.
  • Asthma is the most common disease of lungs. An attack happens when your airways narrow.
  • At the time of birth, we all had pink lungs but as we grow and breathe in the polluted air, our lungs get darker in colour.
  • Your lungs are the only human body organ that can float on water.
