It is the newest organ interstitium that scientists have recently discovered and described in the human body. fleshy, not a solid organ. This organ is a network of small, sensitive liquid-filled sacs.

Where is the new organ?

You may know that there is a layer of tissue just below our skin. This tissue; it is also found in the lungs, excretion, digestive tracts and a significant part of the circulatory system. In the past, it was thought to be nothing more than a dense layer of connective tissue, but recent findings from a reputable journal revealed that the tissue was in fact a network of small interconnected small compartments.

All Over The Body

Interstitium is a contiguous area filled with a structural barrier, such as skin, that exists between internal structures such as organs and muscles. It is a series of microscopic, liquid-filled sacs that are basically all around our body. Interstitium is actually a vast structure that is present all over our body. It is so large that it can be called an organ on its own. In this way it can be said that it is larger than other organs. Estimates are that about 20 percent of the volume of tissue interstitial fluids is present in the interstitium of approximately 10 liters.

80th Organ in the Human Body

Although the presence of interstitial tissue and fluid by scientists and physicians previously known, an intense connective tissue was considered, and the anatomy could not be identified. Recent studies have found that this structure is not only a dense connective tissue, but has a compressible liquid and has been considered as a separate organ. The fluid-filled compartments are connected to the elastin and collagen network. After the 79th ud mesenter sonra discovered in 2017, the interstitium became the 80th organ of the human body.

Functions of Interstitium

Although scientists are not fully confident in the functions of the interstitium, they predict that these sacs function as little shock absorbers for the body. In simple terms, these fluid-filled voids are located on the outer membrane of the organs such as the lung, heart, muscle and blood vessels, intestines, and wrap them around like a net with a flexible, strong structure, preventing damage and tearing.

Why Interstitium is Discovered Late?

Medical researchers published their findings on interstitium in Scientific Reports in March 2018. It is a matter of wonder why such an important structure has not been noticed until now. Until now, interstitium has not been identified as a separate entity because of the tools used to study the tissues beneath the skin. Fixed tissues are treated with chemicals by scientists, finely cut and sliced, and the remaining liquids are flushed and then ready for examination by medical microscopes. This method leads to collapse of the liquid-filled sacs and makes the supporting connective tissue visible. Therefore, the histological and anatomically unexplained organ is overlooked because the organ, whose existence is currently accepted, has been missed.
A new technique of probe-based confocal laser endomicroscopy recently performed by researchers at New York University yielded a different type of microscopic image. The researchers found a network of fluid-filled sacs while examining the bile duct of a cancer patient. Thus, the interstitium was identified and identified as a separate structure from the connective tissue.

Hopes are Rising

The fluid in the interstitium returns to the lymphatic vessels and is in direct contact with the lymph nodes. Therefore, cancerous cells enter the lymphatic system via intersittium. It is thought that new tests related to cancer can be developed as the functions of our new organ are understood. The hopes that this organ may illuminate the spread of cancer in the body have increased.
