👉 Rat fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the central nervous system of rats. It plays a crucial role in maintaining the health of the brain and spinal cord by providing essential nutrients, removing waste products, and cushioning neural tissues from mechanical shocks. Produced by the choroid plexus in the brain, rat fluid circulates through the ventricles, bathed in the subarachnoid space surrounding the brain and spinal cord. This fluid helps regulate intracranial pressure, supports the transport of ions and molecules necessary for neuronal function, and acts as a medium for immune defense against pathogens. Its constant movement ensures that the nervous system remains well-hydrated and protected.
