Cerebrospinal Fluid (CSF): Circulation of CSF
Choroid plexus of lateral ventricle (phantom) Superior sagittal sinus
CSF circulates through the four brain ventricles (two lateral ventricles and a third and fourth ventricle) and in the subarachnoid space surrounding the brain and spinal cord. Most of the CSF is reabsorbed into the venous system through the arachnoid granulations and through the walls of the capillaries of the central nervous system and pia mater.
