urine (u´rin)   the fluid containing water and waste products that is secreted by the kidneys, stored in the bladder, and discharged by way of the urethra. Several different types of waste products are eliminated in urine, such as urea, uric acid, ammonia, and creatinine; none are useful in the blood. The largest component of urine by weight (apart from water) is urea, which is derived from the breakdown of dietary proteins and amino acids in the diet as well as those of the body itself.
