Urine is an aqueous solution of electrolytes and metabolites excreted by mammals, birds, reptiles, fish and amphibians. Although urine is excreted as a paste (uric acid) by most birds, it is commonly excreted as a fluid varying in color from clear, when diluted, to a dark amber, when concentrated. Urine is produced by the kidneys, and plays a vital role in maintaining homeostasis by removing excess water.
The chemical formula for urine is (NH2)2CO + H2O → CO2 + 2NH3.
Urine can also be used as fertilizer because of the bacteria, hormone -testerone, and glucose. Urine also carries dissolved metal materials, such as copper, zinc, lead, chromium, and cadmium.
