Your Answer:
a barrier that prevents most particles from entering the CNS tissue

The blood-brain barrier is a diffusion barrier which prevents
most particles from entering the central nervous system
tissue, keeping the brain and spinal cord separate from
general blood circulation. The blood-brain barrier is formed
by the relatively impermeable brain capillaries, due to the
glial cells astrocytes. Maintenance of the blood-brain-barrier
is important to provide a stable chemical environment for
the nervous system.
