👉 A natural fluid, often referred to as a bodily fluid or simply fluid, is any substance that circulates within the body, typically in a liquid state, serving essential roles in maintaining physiological functions. These include transporting nutrients, oxygen, hormones, and waste products; lubricating joints; cushioning organs; and facilitating chemical reactions. Examples include blood, lymph, synovial fluid, cerebrospinal fluid, and synovial fluid. Each type of natural fluid plays a unique role in sustaining health, with blood being the most prominent due to its extensive circulation throughout the body.
