Quizplus · Accepted Answer

The BBB is a selective mechanism that prevents harmful substances, including toxins and infections, from entering the brain from the bloodstream. This barrier is formed by tightly-packed cells that line the blood vessels in the brain, which prevents large molecules and toxic substances from passing through. Therefore, the BBB plays an important role in protecting the brain from potential damage.
