3. CSF produced by the choroid plexus circulates through the ventricular system and into the subarachnoid space.
4. The choroid plexus acts as a barrier, protecting the brain from potentially harmful substances in the blood.
5. Proper functioning of the choroid plexus is essential for maintaining intracranial pressure and overall neural health.
