Scientists have discovered a new human organ

The accidental find highlights just how much there is still left to learn about the workings of the human body.
The new organ, which has been christened the interstitium, was discovered quite by accident by researchers who had been conducting routine endoscopies - a procedure that involves sending a small camera down a patient's throat to examine the digestive tract.

After examining the bile ducts of several patients using a newer laser-based endoscopy procedure, the scientists discovered a strange mesh-like network of fluid-filled tissue.

Further tests revealed that the interstitium can actually be found throughout the body.
The reason it hadn't been noticed before is because when tissue samples are normally collected, the fluid-filled pockets collapse, creating the illusion of completely solid tissue.

Scientists believe that the interstitium acts as a shock absorber for our internal organs and also serves as an internal highway to carry cells - especially white blood cells - around the body.

"This fixation artifact of collapse has made a fluid-filled tissue type throughout the body appear solid in biopsy slides for decades, and our results correct for this to expand the anatomy of most tissues," said study co-author Neil Theise of New York University's Department of Pathology.

"This finding has potential to drive dramatic advances in medicine, including the possibility that the direct sampling of interstitial fluid may become a powerful diagnostic tool."

The interstitium, the shock-absorbing tissue underneath the skin, gut and blood vessels, has been identified as an organ for the first time according to a new study.  https://www.yahoo.com/news/interstitium-scientists-apos-discover-organ-135955637.html The science article at Nature dot com: https://www.nature.com/articles/s41598-018-23062-6

I'm amazed that such a widespread organ wasn't discovered until now!  I wonder what else is hiding in our bodies awaiting the creation of new instruments to discover?

Now we just have to find a better way to observe the new organ, if you get my drift.

Eastern medicine also alludes to a "hidden organ", but, not the same as this. They (Eastern medicine) suggests that we have a primary and secondary heart. The first is the well-known, classical heart. The second "heart" is alluded by them to be directly related to certain biological tissues surrounding the human spine. These tissues purportedly have a "pumping" action, assisting the primary heart. Thus the emphasis within Eastern medicine of spinal health and suppleness through Yoga exercise. How much of this is true I do not know, but thought to share... so don't beat me over the head.
