I believe it is called Passive Transport, if I am not mistaken.

Ciliated ependymal cells:<u> circulate cerebrospinal fluid.</u>
Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
- They are part of glial cells, which share space with neurons in the nervous system.
- They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.
- For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.
- The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.
- A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.
Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.
