Researchers have detailed the structure and distribution of spaces in your body that they say represent a newfound human organ , and this "organ" just might be your body's biggest -- but not all experts are convinced. The skin, comprising roughly 16% of your body mass , is thought to be your largest organ . "It would be analogous to discovering blood vessels for the first time, in that they are in every organ but they aren't an organ themselves," Nathanson said. Since interstitium spaces might act as conduits, "this raises the possibility that direct sampling of the interstitial fluid could be a diagnostic tool," the researchers wrote. The interstitium could change the way doctors think about not only cancer but also potentially other diseases and many functions within the body, Theise said.
