👉 Rats' fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system. This fluid serves multiple critical functions: it cushions and protects the brain and spinal cord from mechanical injury, removes waste products from neural tissues, and provides a medium for the exchange of nutrients and gases. Produced by the choroid plexus in the brain's ventricles, CSF flows through the ventricular system, then into the subarachnoid space surrounding the brain and spinal cord. It exits through the arachnoid villi into the venous system, maintaining a delicate balance essential for optimal neurological function.
