(U"rine) n. [F. urine, L. urina; akin to urinari to plunge under water, to dive, Gr. urine; cf. Skr.
var water, Icel. r drizzling rain, AS. wær the sea.] (Physiol.) In mammals, a fluid excretion from the
kidneys; in birds and reptiles, a solid or semisolid excretion.
In man, the urine is a clear, transparent fluid of an amber color and peculiar odor, with an average density
of 1.02. The average amount excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters).
Chemically, the urine is mainly an aqueous solution of urea, salt and uric acid, together with some hippuric
acid and peculiar pigments. It usually has an acid reaction, owing to the presence of acid phosphates
of soda or free uric acid. Normally, it contains about 960 parts of water to 40 parts of solid matter, and
the daily average excretion is 35 grams (540 grains) of urea, 0.75 gram (11 grains) of uric acid, and
16.5 grams (260 grains) of salt. Abnormally, it may contain sugar as in diabetes, albumen as in Bright's
disease, bile pigments as in jaundice, or abnormal quantities of some one or more of the normal constituents.
