Explanation:
Detailed explanation-1: -The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.
Detailed explanation-2: -Unlike the capillaries that form the blood-brain barrier, choroid plexus capillaries are fenestrated and have no tight junctions.
Detailed explanation-3: -The CSF is secreted by the choroid plexus, a tissue located in each ventricle in the brain. CSF flows from the lateral ventricles to the third and fourth ventricles, then into the subarachnoid space of the brain and spinal cord via openings (foramena) below the cerebellum.
