Human Cerebrospinal Fluid:

 Cerebrospinal fluid is a clear, colourless liquid that fills and environs the brain and the spinal cord and delivers a motorized barrier against shock. Fashioned principally in the ventricles of the brain, the cerebrospinal fluid provisions the brain and provides lubrication between surrounding bones and the brain and spinal cord. When a person agonizes a cranium injury, the fluid acts as a beanbag, deadening the force by allocating its impact. The fluid helps to uphold compression within the cranium at a constant level. An upsurge in the volume of blood or brain tissue results in a consistent decrease in the fluid. Equally, if there is a decrease in the volume of matter within the cranium, as occurs in atrophy of the brain, the CSF compensates with an increase in volume. The fluid also conveyances metabolic waste products, antibodies, chemicals, and pathological products of disease away from the brain and spinal-cord tissue into the bloodstream. Cerebrospinal fluid is somewhat alkaline and is around 99 percent water. There are around 100 to 150 ml of cerebrospinal fluid in the ordinary adult human body.
