(FOX NEWS) — A group of scientists recently discovered an organ you didn’t know you had.
While performing endoscopies — a non-surgical procedure where a small camera attached to a tube is used to examine the gastrointestinal tract — scientists came across what they now call the “interstitium.” The organ is a “previously unappreciated fluid-filled interstitial space, draining to lymph nodes and supported by a complex network of thick collagen bundles,” according to the study’s authors.
