👉 Inn fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless, and slightly yellowish liquid that circulates within the central nervous system (CNS), comprising the brain, spinal cord, and their surrounding spaces. This vital fluid serves multiple essential functions: it cushions the brain and spinal cord from physical impacts, maintains a stable chemical environment by regulating ion concentrations and removing waste products, and facilitates the transport of nutrients to neural tissues. Produced by the choroid plexus in the ventricles of the brain, inn fluid circulates through the subarachnoid space surrounding the brain and spinal cord, ensuring optimal functioning and protection of these critical organs.
