👉 The Frank Fluid, also known as interstitial fluid or extracellular fluid, is a critical component of the human body's fluid system. It fills the spaces between cells and within the cavities of tissues, making up about 55% of total body water. This fluid is essential for nutrient transport, waste removal, and maintaining the structural integrity of tissues. It also plays a vital role in cellular metabolism and communication, as it facilitates the exchange of substances between cells and the bloodstream. The Frank Fluid is constantly being produced and reabsorbed, ensuring a dynamic balance that supports overall physiological functions.
