Ventricular System

The ventricular system is comprised of a series of four cavities in the brain that produce cerebrospinal fluid (CSF). These cavities (called ventricles) are filled with CSF and it flows through the four cavities and the spinal cord.. The CSF helps protect the brain and spinal cord by cushioning it from impact. The CSF also allows the brain to 'float' within the skull which helps protect against impacts and the effects of gravity. In addition to protection against impacts the CSF provides nutrients to the brain.
