The official world record for the longest hair is held by Xie Qiuping of China, whose hair was measured in 2004 at 4.2 meters (14 ft) long. If Hay's hair was as long as it is claimed to be â or even as long as the 6.2 meters that was reported in 2006 â it would have taken the record by a considerable distance.
The lungs are among the hardest-working organs in the body. They expand and contract up to 20 times a minute to supply oxygen to be distributed to tissues all over the body and expel carbon dioxide that has been created throughout the body.
Oxygen is a gas that your body needs to work well. Your lungs take the oxygen out of the air you breathe and put it into your blood. The blood takes the oxygen to all the cells in your body. Then the waste carbon dioxide is taken back to the lungs where you breathe it out.
