Blood brain barrier

Authoring team

Oxygen, glucose, and certain ions pass rapidly from the circulating blood into brain cells. Other substances e.g. urea, creatinine, chloride, insulin and sucrose, pass quite slowly. Some substances do not pass from the blood into the brain e.g. proteins. The differential rates of passage of certain materials into most parts of the brain is termed the blood-brain barrier.
