glymphatic and lymphatic even though their job is the same "clean up" i don't think they are quite the same.
In most of the body, a network of vessels carry lymph, a fluid that removes excess plasma, dead blood cells, debris and other waste. But the brain is different. Instead of lymph, the brain is bathed in cerebrospinal fluid. For decades, however, neuroscientists have assumed that this fluid simply carries soluble waste by slowly diffusing through tissues, then shipping its cargo out of the nervous system and eventually into the body’s bloodstream. Determining what’s really going on has been impossible until recently.
here is a link about the lymph and immune-notice the many lymph vessels-also as 1eye said they could be impacting the veins and arteries. it sure is important but you don't hear much on it. but if it's not working right it screws with pretty much everything.www.innerbody.com/image/lympov.html
