👉 The regarded fluid, often referred to as the cerebrospinal fluid (CSF), is a clear, colorless liquid that surrounds and protects the brain and spinal cord. It acts as a cushion, absorbing shocks and reducing friction between these vital organs during movement. CSF also plays a crucial role in maintaining the brain's internal environment by regulating temperature, nutrient delivery, and waste removal. Additionally, it helps in the transport of nutrients and signaling molecules to and from the central nervous system. This fluid is continuously produced in the ventricles of the brain and flows through the ventricular system, then into the subarachnoid space surrounding the brain and spinal cord, before being reabsorbed into the bloodstream via the arachnoid villi.
