Explanation:
The cerebrospinal fluid (CSF) is the fluid of the central nervous system. It allows for buoyancy as the brain is immersed in the fluid, protection, excretion of waste products from the brain and many more. The production of CSF is by the CHORIOD PLEXUS in the lateral, third and fourth ventricles. The CSF flows through the interventricular foramen from the lateral to the third ventricle and from the third ventricle into the fourth ventricle through the cerebral aqueduct which connects them. The CSF then flows into the subarachnoid space. Absorption of CSF into the blood is by the arachnoid villi and then the CSF enters the blood.
