Cells of Capillaries That Nourish the Cells of the Central

Cells of capillaries that nourish the cells of the central nervous system are joined by tight junctions, whereas the capillaries to most other organs are characterized by having large openings or clefts between adjacent cells. How would the difference in cell- cell connections affect their functions?

A) There is more pressure on the blood passing through the central nervous system than to other organs.
B) The blood-brain barrier is more selective regarding the types of molecules that can pass out of circulation.
C) Capillaries of the blood-brain barrier are more likely to rupture.
D) Capillaries of the central nervous system are more tightly anchored to adjacent tissues.
