Final answer:
Cerebrospinal fluid (CSF) supports the weight of the brain, removes waste from brain cells, and cushions the brain, but it does not transport blood to brain structures.
Step-by-step explanation:
Cerebrospinal fluid (CSF) has several important functions, including supporting the weight of the brain, removing waste from brain cells, and cushioning the brain. However, it does not transport blood to brain structures. CSF is produced in the ventricles of the brain, circulates throughout the central nervous system, and is reabsorbed by the bloodstream. Its primary role is to provide protection and nourishment to the brain and spinal cord.
