One team had expected to find that the bile duct is surrounded by a hard, dense wall of tissue. But instead, they saw weird, unexplained patterns. They took their findings to Neil Theise, a pathologist at New York University School of Medicine.Shock absorbersWhen Theise used the same endomicroscopy device to look under the skin of his own nose, he saw a similar result. Further investigation of other organs suggested that these patterns are made by a type of fluid moving through channels that are everywhere in the body.Theise reckons that every tissue in the body may be surrounded by a network of these channels, which essentially form an organ. The team estimate that the organ contains around a fifth of the total fluid volume of the human body. "We think they act as shock absorbers," says Theise.This organ was likely never seen before because standard approaches for processing and visualising human tissue causes the channels to drain, and the collagen fibres that give the network its structure to collapse in on themselves. This would have made the channels appear like a hard wall of dense protective tissue, instead of a fluid-filled cushion.[/quotehttps://www.newscientist.com/article/2164903-newly-discovered-human-organ-may-help-explain-how-cancer-spreads/Mind blowing actually
Huh, isn't this just a form of Areolar connective tissue?http://www.ivyroses.com/HumanBody/Tissue/Tissue_Areolar-Tissue.phphttps://en.wikipedia.org/wiki/Loose_connective_tissue

I find it hard to believe nobody has ever "discovered" this huge" organ" before.
It was known all right, but because of the preparation methods for microscopy, it was regarded as just supporting, solid tissue. The way I read articles, new methods not crushing the samples revealed the inner, fluid filled, structures.
"It is fair to say that histologists [and] pathologists have long known that there is an interstitial space and that it contains fluid," Anirban Maitra, a pathologist at the University of Texas MD Anderson Cancer Center who did not participate in the work, writes in an email to The Scientist. "The claim that it is a hitherto undiscovered organ, and the largest one ever at that, seems a stretch," he cautions."Most biologists would be reticent to put the moniker of an 'organ' on microscopic uneven spaces between tissues that contain fluid. By this definition, the abdominal cavity and pleural spaces should be discrete organs" too, says Maitra.
