👉 Releases fluid, commonly known as cerebrospinal fluid (CSF), is a clear, colorless, and slightly yellowish liquid that circulates around the brain and spinal cord. This fluid acts as a protective cushion, providing mechanical support and reducing friction between the brain's surface and the skull. It also plays a vital role in nutrient delivery and waste removal, maintaining an optimal environment for neural function. CSF is produced by the choroid plexus in the ventricles of the brain and flows through the ventricular system, then enters the subarachnoid space surrounding the brain and spinal cord. From there, it exits through arachnoid villi into the venous system, completing its cycle and ensuring the health and functionality of the central nervous system.
