Urine is primarily composed of water, accounting for about 95% of its volume. The remaining 5% consists of waste products, including urea, creatinine, uric acid, and ammonia, as well as electrolytes such as sodium, potassium, chloride, and bicarbonate. The color and odor of urine can vary depending on factors such as hydration status, diet, and the presence of certain medications or medical conditions. Normally, urine is pale yellow to amber in color, and has a relatively mild odor.
