Scientists discover new organ spanning the ENTIRE human body that acts as a built-in 'shock absorber'


  • Researchers have identified a new organ they've dubbed the 'interstitium'
  • This is a network of interconnected, fluid-filled spaces all over the body
  • It can be found beneath the skin's surface, and lining other organs and muscles
  • These compartments may act as shock absorbers to protect our tissues
  • The findings could also help to explain how cancer spreads through some areas 

Dubbed the ‘interstitium,’ interconnected compartments act like a ‘highway of moving fluid’ that sits beneath the top layer of the skin.

It also lines the digestive tract, lungs and urinary systems, and surrounds the arteries, veins, and the fascia between muscle.   

The interstitium is made up of both strong (collagen) and flexible (elastin) connective tissue proteins, with interstitial fluid moving throughout.

The system drains into the lymphatic system, and is said to be the source of lymph, which is vital to the functioning of inflammation-causing immune cells
