👉 The conscious fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that fills the central nervous system, comprising about 20% of an adult's total body weight. This fluid acts as a protective cushion for the brain and spinal cord, providing nutrients and removing waste products. It also plays a crucial role in maintaining the stability of the brain's environment by regulating its temperature and pH levels. Despite being a part of the body's internal fluid system, the conscious fluid is not directly involved in conscious thought processes; instead, it supports the brain's function by ensuring optimal conditions for neural activity.
