👉 Cet 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 and spinal cord. It plays a crucial role in maintaining the health of neural tissues by providing essential nutrients, removing waste products, and cushioning the brain and spinal cord against mechanical shocks. Produced by the choroid plexus in the ventricles of the brain and filtered through the arachnoid villi into the bloodstream, cet fluid also helps regulate intracranial pressure and supports the proper functioning of the nervous system by maintaining a stable chemical environment.
