Final answer:

Cerebrospinal fluid is essential for cushioning the brain, maintaining proper pressure, and protecting it from damage.


Explanation:

Cerebrospinal fluid (CSF) is crucial for providing buoyancy to the brain and protecting it inside the skull. Without CSF, the brain's weight would crush cells and blood vessels at the base of the brain, leading to severe damage. Additionally, CSF helps circulate nutrients, remove waste products, and maintain proper pressure levels within the brain, preventing conditions like hydrocephalus.
