What is the function of spinal fluid?

surrounds and protects the backbone
lines the mucus membrane
increases blood flow
keeps the brain dry and warm

I think the best answer is that the spinal fluid surrounds and protects the backbone. Also, it protects the brain from trauma. It acts as a shock absorber. It supplies nutrients to the nervous system tissue and removes waste products from the brain.
