这个词是什么意思？
A vascular waste clearance system in the brain analogous to the lymphatic system that facilitates transporting of solutes and waste products from CEREBROSPINAL FLUID (CSF) and brain INTERSTITIAL FLUID (ISF). CSF from the SUBARACHNOID SPACE enters the brain periarterial spaces, into the interstitium via channels (e.g., AQUAPORIN 4 PROTEIN) on astrocytic endfeet and exchanges with brain ISF before perivenous drainage of solutes and waste.
