WebMay 1, 1972 · The past ten years have witnessed an increasing interest in the regulation of the cerebrospinal fluid (CSF) pH.Part of this interest stems from the fact that the extracellular fluid (ECF) pH in the brain serves as an important regulator of pulmonary ventilation [1–4] and a major determinant of cerebral blood flow [5–10].Furthermore, … WebThe total volume of CSF is 150 mls. The daily production is 550 mls/day so the CSF turns over about 3 to 4 times per day. The CSF is formed by the choroid plexus (50%) and directly from the walls of the ventricules (50%).
