👉 The di fluid, also known as the di fluid of the brain, is a complex mixture of water, electrolytes, proteins, lipids, and various biochemical substances that circulate within the brain's extracellular space. This fluid plays a crucial role in maintaining the brain's homeostasis, facilitating nutrient delivery to neurons, and removing metabolic waste products. It also supports the formation of the blood-brain barrier, a selective permeability barrier that protects the brain from harmful substances while allowing essential nutrients to pass through. The di fluid's composition is tightly regulated by the brain's microenvironment, and any imbalance can lead to neurological disorders.
