👉 The identifying fluid, also known as the "cerebrospinal fluid" or CSF, is a clear, colorless liquid that circulates within the central nervous system (CNS) of vertebrates, including humans. It acts as a protective cushion, reducing the impact of physical shocks on the brain and spinal cord, and maintaining a stable chemical environment around these critical organs. CSF also plays a vital role in nutrient transport, waste removal, and the regulation of intracranial pressure. Produced by the choroid plexus in the ventricles of the brain, it flows through the ventricular system and into the subarachnoid space surrounding the spinal cord, eventually draining back into the bloodstream via four main pathways: the longitudinal and transverse sinuses.
