what body system are the ventricles of the brain in?
The ventricular system is a set of four interconnected cavities in the brain, where the cerebrospinal fluid is produced. Within each ventricle is a region of choroid plexus, a network of ependymal cells involved in the production of CSF. The ventricular system is continuous with the central canal of the spinal cord allowing for the flow of CSF to circulate. All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium.
