Quizplus · Accepted Answer

The blood-brain barrier is a structural feature of the brain that regulates the movement of materials from the blood into the brain. It consists of specialized cells that line the blood vessels in the brain and prevent certain substances from passing from the blood into the brain, while allowing necessary nutrients and oxygen to enter. This helps to protect the brain from harmful substances and maintain a stable environment for proper brain functioning.
