👉 The "Sons' Fluid," also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system, specifically around the brain and spinal cord. It acts as a protective cushion, providing nutrients and removing waste products from neural tissues. This fluid is produced by the choroid plexus in the ventricles of the brain and flows through the subarachnoid space, surrounding the brain and spinal cord, before being absorbed into the bloodstream via arachnoid villi. The fluid's movement is crucial for maintaining a stable environment for the nervous system, facilitating the transport of essential molecules and removing metabolic waste.
