Summary Introduction

Introduction:

Epithelial cells of the capillary wall form a highly selective semipermeable border that involves the separation of the circulating blood from the brain and extracellular fluid in the CNS (central nervous system), and is known as the blood–brain barrier. This barrier involves the movement of water, some gases, and liquid soluble molecules by passive diffusion.
