Scientists have discovered a new organ called the "interstitium" that may act as a shock absorber for vital organs and tissues. This organ is a network of fluid-filled compartments found beneath the skin and lining the gut, lungs, blood vessels, and muscles. Previously, these spaces were thought to be solid, but advanced imaging technology revealed that they are interconnected, allowing fluid to flow and help distribute the body's fluid balance. The interstitium may play a role in how diseases spread, potentially leading to new treatments in the future.
