Question

Quizplus · Accepted Answer

Astrocytes are a type of glial cell in the brain that provide structural support and help regulate the chemical environment of the brain. They also play a role in protecting the brain from harmful substances by forming a barrier between the blood vessels and the brain tissue, known as the blood-brain barrier. This barrier helps prevent toxins, viruses, and other harmful substances from entering the brain and causing damage.
