👉 The sense fluid, also known as cerebrospinal fluid (CSF), is a clear, colorless liquid that circulates around the brain and spinal cord. It acts as a protective cushion, providing physical support and cushioning to these vital organs, absorbing shocks from movements and impacts. Additionally, it plays a crucial role in maintaining the brain's internal environment by regulating temperature, nutrient delivery, and waste removal. The fluid also aids in the transport of nutrients and hormones and helps remove metabolic waste products, ensuring optimal brain function.
