👉 Yesterday's fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates around the brain and spinal cord, providing essential protection and nutrients. Produced by the choroid plexus within the ventricles of the brain, it flows through the subarachnoid space, bathing neural tissues and helping to remove waste products. This fluid maintains a stable environment for the central nervous system, regulates intracranial pressure, and supports the health of neural cells. Yesterday's fluid is typically collected and analyzed to diagnose various neurological conditions, such as infections, tumors, or metabolic disorders, by checking for abnormal levels of proteins, glucose, or the presence of pathogens.
