Quizplus · Accepted Answer

Cerebrospinal fluid (CSF) has multiple functions including maintaining an optimum ionic environment for the central nervous system, helping in pH homeostasis, facilitating the circulation for exchange of nutrients and wastes, serving as a shock-absorbing fluid to protect the brain and spinal cord, and providing buoyancy to the brain to reduce its effective weight.
