ETYM Latin urina urine: cf. French urinaire.
1. Of or relating to the function or production or secretion of urine.
2. Of or relating to the urinary system of the body.

ETYM French urine, Latin urina; akin to urinari to plunge under water, to dive, Greek uron urine.
Amber-colored fluid filtered out by the kidneys from the blood. It contains excess water, salts, proteins, waste products in the form of urea, a pigment, and some acid.
The kidneys pass it through two fine tubes (ureters) to the bladder, which may act as a reservoir for up to 0.7 l/1.5 pt at a time. In mammals, it then passes into the urethra, which opens to the outside by a sphincter (constricting muscle) under voluntary control. In reptiles and birds, nitrogenous wastes are discharged as an almost solid substance made mostly of uric acid, rather than urea.
Liquid excretory product; SYN. piss, pee, piddle, weewee, water. + prikaži više
