Urine (from Latin Urina, ae, f.) is a typically sterile liquid by-product of the body secreted by the kidneys through a process called urination and excreted through the urethra. Cellular metabolism generates numerous by-products, many rich in nitrogen, that require elimination from the bloodstream. These by-products are eventually expelled from the body in a process known as micturition, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis. Certain disease conditions can result in pathogen-contaminated urine.

Famous quotes containing the word urine:

    There seems to be no stopping drug frenzy once it takes hold of a nation. What starts with an innocuous HUGS, NOT DRUGS bumper sticker soon leads to wild talk of shooting dealers and making urine tests a condition for employment—anywhere.
    Barbara Ehrenreich (b. 1941)
