👉 The const fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that acts as a protective cushion for the brain and spinal cord, providing essential support and nourishment. It is produced by the choroid plexus in the ventricles of the brain and circulates through the ventricular system, eventually draining into the subarachnoid space surrounding the spinal cord. This fluid helps maintain a stable environment for neural function, removes waste products, and aids in the regulation of intracranial pressure. Its unique properties make it crucial for the health and proper functioning of the central nervous system.
