Explanation:

Cerebrospinal fluid (CSF) does not provide oxygen and nutrients to the nervous tissue. This is the role of blood vessels. CSF regulates the chemical environment, rinses metabolic wastes, protects the brain from jolts, and helps the brain with its weight.

To provide oxygen and nutrients to the nervous tissue
