Amazing Lung Facts

  • At rest, a person breathes about 14 to 16 times per minute. After exercise it could increase to over 60 times per minute.
  • New babies at rest breathe between 40 and 50 times per minute. By age five it decreases to around 25 times per minute.
  • The total surface area of the alveoli (tiny air sacs in the lungs) is the size of a tennis court.
  • The lungs are the only organ in the body that can float on water.
  • The lungs produce a detergent-like substance which reduces the surface tension of the fluid lining, allowing air in.
