With all that's known about human anatomy, you wouldn't expect doctors to discover a new body part in this day and age. But now, researchers say they've done just that: They've found a network of fluid-filled spaces in tissue that hadn't been seen before.
These fluid-filled spaces were discovered in connective tissues all over the body, including below the skin's surface; lining the digestive tract, lungs and urinary systems; and surrounding muscles, according to a new study detailing the findings, published today (March 27) in the journal Scientific Reports.
maybe this is somewhat related to "weird" things we know from IMA. Expand, contract, qi, jin, etc., etc.
