Explanation The importance of the blood-brain barrier is as follows: 1) It acts as a barrier due to the presence of several tight junctions between the cells of capillaries. This prevents water and other molecules from passing through the spaces between the cells. Also, the endothelial cells of capillaries have a limited capability to perform exocytosis and endocytosis, thus preventing any exchange of substances between blood and extracellular fluid of the brain. 2) Most of the chemicals and disease-causing microorganisms (such as virus and bacteria) are unable to cross the BBB, thus it acts as a component of immunity...
