👉 A reserved fluid, often found within the body's cavities and organs, is a term used to describe fluids that are not readily accessible for immediate medical intervention but serve crucial physiological functions. These fluids, like cerebrospinal fluid (CSF) in the brain or synovial fluid in joints, provide essential protection, lubrication, and nutrient supply to tissues. Unlike other bodily fluids that are actively circulated or drained, reserved fluids are stored and can be mobilized when needed, such as during injury or inflammation, to maintain homeostasis and support organ function. Their reserve status underscores their importance in sustaining vital processes even when immediate access is not possible.
