Amazing Body of Facts : The human body consists of 100 trillion cells approximately which is basic unit of life. These cells are organised biologically to eventually form the whole body. Following are the body of facts that will never cease to amaze

1. There are 300,000 million capillaries in a human lung. If they are joined end to end, it will cover the distance between Delhi and Chennai.

2. For every 500 gm of fat gained, our body makes 11 km of blood vessels. It puts a lot of strain on our heart because it has to work harder to pump blood to these newly created extra vessels. Our body re-absorbs the unnecessary vessels if it loses fat.

3. An adult human body is made up of 7 octillion atoms. It is equal to 7xl02, the number of atoms (1 octillion = 1000 trillion).

4. A normal human cell consists of 23 pairs of chromosomes in its nucleus, which is a molecule of DNA. Chromosome 1 is the biggest and contains 10 billion atoms. It is the largest storehouse of information that is encoded in the molecule.
