CSF flows from the lateral ventricles via the foramina of Monro into the third ventricle, and then into the fourth ventricle

CSF (Cerebrospinal Fluid) is a clear fluid that surrounds the brain and spinal cord, providing several important functions. It acts as a protective cushion for the brain, helps maintain a stable environment for neural tissue, and assists in the removal of waste products from the central nervous system (CNS).

However, CSF itself does not directly remove by-products of metabolism. The primary role of CSF is to provide mechanical and biochemical protection to the CNS. The removal of waste products of metabolism, such as metabolic by-products and toxins, is primarily carried out by other systems in the body, such as the lymphatic system and the blood-brain barrier.

Therefore, the correct answer is Option 3.
