If you slice the entire body of a child, take out all the blood vessels in his body and assemble them in a straight line, the line would be about 58,980 miles long. An adult’s vessels would be about 99,998 miles long. The circumference of the earth is taken as 24901 miles which means that vessels of the adult can go around the earth’s border more than 4 times.

 2. Stars in the galaxy versus your body cells

Now, ponder upon the fact that the neuron is about 100 microns in length with no engine, tires or suspension but it performs the function with the same speed as the fastest car on the earth.

The human retina has about 100 million rods for black and white vision and 7 million cones for color vision. So, per eye, a rough estimate is; 100 megapixels for black and white and 7 megapixels for color.

 


9. Spacious lungs

The inner surface of the lungs can be stretched; they would take an area of 80 to 100 square meters which is about the size of half of the tennis court. This means you can play full court tennis by using your both lungs.
