How would decreased diffusion across the arachnoid granulations affect the volume of cerebrospinal fluid in the ventricles?
A) Decreased diffusion across the arachnoid granulations would decrease the volume of CSF in the ventricles because less CSF would reenter the bloodstream.
B) Decreased diffusion across the arachnoid granulations would decrease the volume of CSF in the ventricles because more CSF would reenter the bloodstream.
C) Decreased diffusion across the arachnoid granulations would increase the volume of CSF in the ventricles because less CSF would reenter the bloodstream.
D) Decreased diffusion across the arachnoid granulations would increase the volume of CSF in the ventricles because more CSF would reenter the bloodstream.
E) Decreased diffusion across the arachnoid granulations would not change the volume of CSF because the amount of CSF reentering the bloodstream can accommodate for the changes.
