👉 A cumulative fluid refers to the total volume of fluid that accumulates in the body over time, primarily from water and electrolytes. This fluid is essential for various physiological functions, including maintaining blood volume, regulating body temperature, aiding in digestion, and lubricating joints. The body continuously loses fluids through processes like sweating, breathing, urination, and bowel movements. To maintain homeostasis, the body must replenish these lost fluids, ensuring that the cumulative fluid level remains within a narrow, optimal range. This balance is crucial for proper organ function and overall health.
