🎀Location : Ventricles and subarachnoid spaces

🎀Formation : choroid plexus(->blood vessel cluster) in the ventricles fiterates bloods to form CSF

 

(layers of choroid plexus)

-->  ventricle spaces

--> cuboidal epthelial tissue

--> blood vessel

 

-cuboidal epithelial tissue attract Na+, Cl-, HCO3- from the capillaries by polarized electrical charge (specialised)

-This makes osmolarity increase in ventricles and water flows toward the ventricles

-There's also small amount of aminoacid, proteins,glucose 

-Filteration involve no cells (white blood cells, usually monocytes are introduced to CSF directly from the vascular system)

 

🎀 Formed in choroid plexus -> arachnoid granulation transport CSF to the venous sinuses of the brain and return them to the blood stream
