Normal ventricles and hydrocephalus

Normally within the brain there are some cavities named ventricles, where a liquid known as Cerebrospinal Fluid (CSF) is produced. The purpose of this is to protect the brain and spinal cord, acting as a shock absorber. It also carries away disposed materials. The CSF circulates from the ventricles towards a space that exists between the brain and the membranes (meninges) that surround it, from where it is "eliminated", into the blood stream .
