Considering that we have been writing books on anatomy for 475 years, it is remarkable that the human body still surprises scientists.
Researchers led by a team working at the New York Icahn School of Medicine On March 27, the Scientific Reports journal described in detail the discovery of a previously unknown set of fluid networks. These networks were found during a routine procedure in which the esophagus of a patient was looked down with a tiny camera, the so-called endoscopy. A relatively new instrument called Confocal Confocal Laser Endomicroscopy was used to observe bile duct tissue at close range. 196590000] Instead of finding the tissues described in most textbooks, they found a ribbed network of fluid-filled collagen filaments. It seems that when physicians and physiologists first looked at these areas, the tools they used collapsed the collagen and squeezed out all the fluid. To confirm this, the researchers then asked 1
To check the prevalence of these types of tissues, Neil Theise, a pathologist at the New York University School of Medicine and main author of the work, even put the same tool on his own nose, according to New Scientist. Sure enough, the fluid filled matrix was there.
The team thinks we have these structures throughout our bodies, though it's not clear why. One theory is that they behave like upholstery and allow our other organs to comfortably expand and contract while doing their daily business. You may also have something to do with the way tumors spread throughout the body. When cancer cells are taken up by this fluid, they can be quickly absorbed through the lymphatic system "like on a waterslide," said Theise New Scientist. Also inflammatory diseases, certain types of liver disease and other types of swelling could be influenced by these networks.
The jury decides whether this fluid network fulfills the criteria of an organ.
In some schools of thought organs are designated by a specific role. "The stomach, bladder and kidneys are all self-contained areas of tissue that all work together to function," Jennifer Whitney previously told Quartz. The appendix gets a passport, because although we can only theorize what he does, he can become infected. At other times, organs are thought to be basically any solid structure in the body that would exclude blood. But blood can also get sick, like anemia or certain cancers.
In fact, there is not a single definition of an organ – it depends on the person who classifies it. But that is not so important. These scientists are more focused on understanding how these newly spotted structures affect our health and whether they can be used as a drug delivery or diagnostic tool.
