👉 Humans' fluid, often referred to as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system, providing essential support and protection to the brain and spinal cord. This fluid acts as a cushion, reducing the impact of physical shocks and maintaining the brain's position within the skull. It also plays a critical role in nutrient delivery, waste removal, and maintaining the chemical balance of the neural environment. The production and circulation of CSF are tightly regulated processes involving the choroid plexus and arachnoid granulations, ensuring a stable internal milieu for optimal brain function.
