Fluids move throughout the body via several paths. The cardiovascular system circulates blood, nutrients, and gases throughout the body. The lymphatic system carries white blood cells and other immune cells through a network of vessels and tissues, including lymph nodes. The lymphatic system also serves as a connection between tissues and the bloodstream, performing several functions such as removing dead blood cells and other waste. | Fluids move throughout the body via several paths.

Researchers recently discovered a series of channels that surround blood vessels within the brain. This system, managed by the brain's glial cells, was termed the glymphatic system. It moves cerebrospinal fluid, a clear liquid surrounding the brain and spinal cord, quickly and deeply throughout the brain, removing waste.The discovery of a pathway for immune cells to exit the [[CNS|central nervous system]] raises the question of whether disruption of this route may be involved in neurological disorders that are associated with immune system dysfunction, such as multiple sclerosis, meningitis, and Alzheimer’s disease.<ref>[source nih.gov/news-events/nih-research-matters/lymphatic-vessels-discovered-central-nervous-system Lymph CNS discovery]</ref> | ||
