Quizplus · Accepted Answer

Alcohol is fat-soluble, which allows it to more easily pass through the blood-brain barrier and affect the central nervous system. Water-soluble substances, on the other hand, have a harder time passing through this barrier. The tendency to be metabolized in the liver (D) and excreted in the urine (C) are related to how the body processes and eliminates alcohol, but they do not explain its ability to cross the blood-brain barrier.
