The choroid plexus and ependymal cells line the ventricles of the brain and are responsible for producing and secreting cerebrospinal fluid (CSF).

The total volume of cerebrospinal fluid in an adult human is typically around 120-150 ml. 200 ml is often cited in some textbooks as the upper limit or approximate value.

The primary function of CSF is to cushion the brain within the skull and serve as a shock absorber for the central nervous system. CSF also circulates nutrients and chemicals filtered from the blood and removes waste products from the brain.

Cerebrospinal fluid circulates in the subarachnoid space, which is the space between the arachnoid mater and the pia mater.

The choroid plexus is specifically responsible for the secretion of cerebrospinal fluid.

The subarachnoid space, located between the pia mater and the arachnoid mater, is filled with cerebrospinal fluid.

The total volume of CSF in the adult ranges from 140 to 270 ml. The volume of the ventricles is about 25 ml. CSF is produced at a rate of 0.2 - 0.7 ml per minute or 600-700 ml per day.

The ventricles of the brain are cavities filled with cerebrospinal fluid, which is produced by the choroid plexus.

The pH of cerebrospinal fluid is slightly alkaline, typically ranging between 7.30 and 7.40, with 7.33 being a commonly cited value.
