👉 The "whose fluid" refers to the cerebrospinal fluid (CSF), a clear, colorless liquid that circulates within the central nervous system. Produced by the choroid plexus in the brain and spinal cord, CSF acts as a protective cushion for the brain and spinal cord, maintaining a stable environment by cushioning these organs, removing waste products, and providing nutrients. It also helps regulate intracranial pressure and aids in the transport of various substances, including hormones and immune cells, between the blood and the central nervous system.
