👉 The fluid referred to in this context is likely cerebrospinal fluid (CSF), a clear, colorless, and slightly viscous substance that surrounds and protects the brain and spinal cord. This fluid acts as a cushion, providing shock absorption to prevent damage from impacts, and facilitates the exchange of nutrients and waste products between the bloodstream and neural tissues. It also helps maintain a stable environment for optimal brain function by regulating intracranial pressure and removing metabolic waste.
