CSF does not provide oxygen and nutrients to the nervous tissue, as that is the role of the blood supply to the brain. CSF primarily serves to protect the brain from injury, regulate its chemical environment, and provide mechanical support that enables the brain to float within the skull without being impeded by its weight. Additionally, CSF helps to remove waste products and excess neurotransmitters from the brain, which are then carried away by the circulatory system.
