U"rine (?), n. [F. urine, L. urina; akin to urinari to plunge under
water, to dive, Gr. &?; urine; cf. Skr. vr 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 (sodium chloride), 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.
