👉 Fluid, often referred to as "dos fluid" in medical contexts, is a broad term used to describe a variety of essential fluids that maintain the body's homeostasis and facilitate various physiological processes. These include blood, plasma, lymph, interstitial fluid, cerebrospinal fluid, and synovial fluid, each serving distinct roles such as transporting nutrients, removing waste, providing cushioning, supporting immune function, and lubricating joints. Proper balance and composition of these fluids are crucial for optimal organ function and overall health, with imbalances potentially leading to conditions like dehydration, edema, or impaired circulation.
