Function of CSF
Cerebrospinal fluid (CSF) primarily functions in supporting the brain, preventing contact between delicate neural structures and surrounding bones, and transporting nutrients and chemical messages. While it does play a role in waste removal to some extent, it is not the primary system for transporting waste products.
The removal of waste from the central nervous system (CNS) is primarily handled by the glymphatic system, which operates in coordination with the circulatory system.
