What protects the CNS from harmful substances and pathogens by preventing passage of these substances from blood into the interstitial fluid of brain tissue?
The blood-brain barrier is a protective mechanism that regulates the passage of substances from the blood into the interstitial fluid of the brain tissue.

This barrier helps protect the central nervous system (CNS) from harmful substances and pathogens.
