Respuesta :

b)It is produced by the choroid plexus of the ventricles in the brain

Explanation:

  • The primary function of chloroid plexus is to produce CSF(Cerebrospinal Fluid) through the ependymal cells that line the ventricles of the brain.
  • Ependymal cells are very essential in CSF production as Chloroid Plexus may secrete up to 500ml of CSF per day in the adult human brain.
  • It also serves as the barrier in the brain separating the blood from CSF and for this, it is called a Blood-CSF barrier of the brain.
