Urine

Urine Formation: Filtration, Reabsorption, and Secretion.
Urine is the means through which the chemicals are filtered out of the body. Urine is a liquid excreted through the urethra that is produced by the kidneys, collected in the bladder, and discharged by the urethra. Urine is used to removing surplus minerals and vitamins from the body, as well as blood corpuscles.
