👉 Chamber fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates within the ventricles and subarachnoid spaces of the brain and spinal cord. This essential fluid acts as a cushion, protecting the delicate neural tissues from mechanical shock and maintaining a stable environment by regulating temperature and nutrient delivery while removing waste products. It also plays a critical role in the brain's homeostasis by facilitating the exchange of substances between the blood and neural tissue. The production and circulation of chamber fluid are tightly regulated by the choroid plexus, a network of blood vessels and specialized epithelial cells lining the ventricles, ensuring a constant supply to support the brain's complex functions.
