Explanation:
Lymph plays a crucial role in the central nervous system (CNS) as it serves as the fluid that bathes tissues and organs.
In the CNS, cerebrospinal fluid (CSF) is the fluid that surrounds the brain and spinal cord, while lymph is what filters out foreign particles and aids in the removal of metabolic wastes.
The lymphatic system returns protein and excess interstitial fluid to the circulation, ensuring a balance in the body's fluid environment.
