Which of the following would not apply to the Blood-Brain Barrier?

Water-soluble substances cross by active transport whereas substances such as creatinine, urea, and most ions, cross very slowly.

Proteins and most antibiotic drugs—do not pass at all from the blood into brain tissue.

It protects the CNS from harmful substances and pathogens by preventing passage of these substances from blood into the interstitial fluid of brain tissue.
