Quizplus · Accepted Answer

Astrocytes are cells that play a key role in the formation of the blood-brain barrier, which helps to protect the brain from harmful substances that may be circulating in the bloodstream. Astrocytes create a physical barrier by wrapping their end-feet around the blood vessels in the brain, limiting the movement of molecules and cells in and out of the brain.
