An excreta material which is composed primarily of urine, a liquid excreta containing water and waste products made by the kidneys, stored in the bladder, and leaves the body through the urethra. ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.
