👉 The Hugh Fluid, also known as the brain's extracellular fluid, is a vital component of the central nervous system. It fills the spaces between cells in the brain and spinal cord, making up about 20% of the total body water. This fluid plays a crucial role in maintaining homeostasis, supporting neuronal function, and removing waste products through the glymphatic system. It is continuously produced by blood vessels and reabsorbed by the lymphatic system, ensuring a delicate balance necessary for optimal brain health.
