I want to know the answer to the following question:
The two main structures that protect the brain are what?
All the background I'm provided with is that "Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage.". Is that enough to answer the question?
Answer: yes
