What is cerebrospinal fluid (CSF) and how does it relate to the ventricles in the brain?

Cerebrospinal fluid (CSF) is a clear, colorless fluid that surrounds the brain and spinal cord, providing cushioning and protection. It is produced in the ventricles of the brain, which are interconnected cavities that help circulate and distribute the CSF throughout the central nervous system. The CSF helps maintain a stable environment for the brain and spinal cord by removing waste products and delivering nutrients.
