👉 The produced fluid, also known as urine, is a complex mixture of water, electrolytes, organic compounds, and waste products that are expelled from the body. It is primarily composed of water (about 95%), along with dissolved salts, glucose, amino acids, urea, creatinine, and various organic and inorganic substances. The production of urine is regulated by the kidneys, which filter blood to remove waste and excess substances, adjusting the concentration of these materials through processes like reabsorption and secretion. This fluid serves essential functions such as maintaining fluid balance, removing toxins, regulating blood pressure, and controlling electrolyte levels in the body.
