What Does the Choroid Plexus Do?

The choroid plexus (ChP) is a secretory tissue found in each of the brain ventricles, the main function of which is to produce cerebrospinal fluid (CSF).

What fluid does the choroid plexus produce?

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.

Does the choroid plexus produce CSF?

The choroid plexus (ChP) is a secretory tissue responsible for producing cerebrospinal fluid (CSF) in the vertebrate brain. CSF flows from the lateral to the third ventricle via the interventricular foramina (also known as the foramen of Monro), and then through the cerebral aqueduct to the fourth ventricle (FIG. 1).
