Urine
Urine (from Latin Urina, ae, f.) is a liquid by-product of the body secreted by the kidneys through a process called urination (or micturition) and excreted through the urethra.Cellular metabolism generates numerous by-products, many rich in nitrogen, that require clearance from the bloodstream. These by-products are eventually expelled from the body during urination, the primary method for excreting water-soluble chemicals from the body. These chemicals can be detected and analyzed by urinalysis.Human urine together with human feces are collectively referred to as human waste or human excreta.
