Ventricles are fluid-filled spaces that contain what?

Explanation:
The ventricles are hollow spaces inside the brain that contain cerebrospinal fluid (CSF). CSF is a clear fluid produced mainly by the choroid plexuses, and it circulates through the ventricular system and around the brain and spinal cord. This fluid cushions the brain, provides buoyancy to reduce its effective weight, helps maintain chemical balance, and aids in waste removal. Blood is carried in blood vessels, not inside the ventricles; air and mucus aren’t present in these brain cavities.
