Scientists Have Finally Discovered Proof That Our Brains Have a Waste Drainage System

Running through your body is a network of channels and junctions called the lymphatic system, which siphons off waste and fluids like a biological sewer.
It was long thought the brain was excluded from this web of anatomical plumbing. After being spotted in mice brains two years ago, researchers have now confirmed the presence of lymphatic vessels in human brains, fueling speculation over the kinds of diseases they might be responsible for.
Way back in 1816, an Italian anatomist by the name of Paolo Mascagni saw what he thought were lymphatic vessels running across the human brain of the cadavers he was dissecting.
