Answer 82

Reabsorption of CSF:

Reabsorbed through arachnoid granulations (villi) and returned to mostly the superior sagittal sinus.

Most of the CSF is transported through vesicles across the cells that line the arachnoid granulations.

The CSF flow is dependent on the higher hydrostatic pressure of CSF compared to venous blood.
