<h3>What is Urine?</h3>
Urine is a liquid byproduct of human and many other animal metabolism. Urine travels from the kidneys to the urinary bladder via the ureters. Urine is discharged from the body through the urethra as a result of urination.
Many by-products of cellular metabolism, such as urea, uric acid, and creatinine, are nitrogen-rich and must be removed from the bloodstream. These by-products are excreted from the body through urination, which is the major way for excreting water-soluble compounds. A urinalysis can identify nitrogenous wastes in mammals.
