Urine


Urine
: Liquid waste. The urine is a clear, transparent fluid. It normally has an amber color. The average amount of urine excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters). Chemically, the urine is mainly an aqueous (watery) solution of salt (sodium chloride) and substances called urea and uric acid. Normally, it contains about 960 parts of water to 40 parts of solid matter. Abnormally, it may contain sugar (in diabetes), albumen (a protein) (as in some forms of kidney disease), bile pigments (as in jaundice), or abnormal quantities of one or another of its normal components.

n.
the fluid excreted by the kidneys, which contains many of the body's waste products. It is the major route by which the end-products of nitrogen metabolism - urea, uric acid, and creatinine - are excreted. The other major constituent is sodium chloride. Over 100 other substances are usually present, but only in trace amounts. Analysis of urine (see urinalysis) is commonly used in the diagnosis of diseases (for example, there are high levels of urinary glucose in diabetes and of ketone bodies in ketonuria); immunological analysis of urine is the basis of most pregnancy test.
