The rate of formation of CSF per day is about?
CSF fills the ventricles and subarachnoid space. In humans, the volume of CSF is about 150 mL and the rate of CSF production is about 550 mL/d. Thus the CSF turns over about 3.7 times a day.It has been estimated that 50-70% of the CSF is formed in the choroid plexuses and the remainder is formed around blood vessels and along ventricular walls.
