There is enough DNA in an average person's body to stretch from the Sun to Pluto and back-17 times.
The human genome, the genetic code in each human cell, contains 23 DNA molecules each containing from 500 thousand to 2.5 million nucleotide pairs. DNA molecules of this size are 1.7 to 8.5 cm long when uncoiled, or about 5 cm on average. There are about 37 trillion cells in the human body and if you’d uncoil all of the DNA encased in each cell and put them end to end, then these would sum to a total length of 2×1014 meters or enough for 17 Pluto round trips (1.2×1013 meters/Pluto round trip).
A Human Organ called Mesentery it connects the intestine to the abdomen and is believed to perform important functions for the body ranging from helping the heart to aid the immune system
