Choroid plexus

What is "choroid plexus"?

The choroid plexus is a specialized network of blood vessels located within the brain's ventricles. It plays a crucial role in the production and regulation of cerebrospinal fluid (CSF), which fills the ventricles and surrounds the brain and spinal cord. The choroid plexus is responsible for the secretion of CSF by selectively filtering blood plasma and releasing it into the ventricles. This fluid provides essential cushioning and support to the brain, helps remove waste products, and supplies nutrients to brain cells. The choroid plexus also contributes to the maintenance of brain homeostasis by regulating the composition and volume of CSF. Its intricate structure and functions make the choroid plexus a vital component of the brain's fluid balance and overall neurological health.
