👉 Extra fluid refers to the additional, often unmeasured, liquid that exists within biological systems beyond what is typically observed or quantified. This fluid can include interstitial fluid, which fills the spaces between cells and tissues in the body, and plasma, a component of blood that circulates throughout the body. The extra fluid plays crucial roles in nutrient transport, waste removal, and maintaining homeostasis. It helps cushion organs, lubricate joints, and facilitates the exchange of substances between cells and their environment. Understanding extra fluid is essential for comprehending various physiological processes and diagnosing conditions related to fluid balance and circulation.
