The blood brain barrier is effective against quizlet

Abstract. The blood-brain barrier (BBB) is a highly selective membrane barrier at the brain microvessel level that facilitates transport between the systemic circulation and the central nervous system. A growing body of evidence supports a major role for the BBB in the etiology and pathogenesis of multiple vascular and neurodegenerative disorders..
