Regarding the blood–brain barrier of the central nervous system (CNS), which of the following statements is incorrect?

a. It exists due to the specific anatomy and transport characteristics of the endothelia cells lining the capillaries of the CNS. b. Lipid-soluble compounds can cross CNS capillary walls only through active or passive transport mechanisms. c. The endothelial cells of CNS capillaries exhibit very few pinocytotic vesicles, limiting the movement of large-molecular-weight compounds into the CNS.

d. None of the above is incorrect.
