Excretion is the process of eliminating waste products of the body. Excretion refers to the elimination of medication from the body. The body has absorbed, distributed, and metabolized the medication molecules - now what does it do with the leftovers? The biliary system contributes to excretion to the degree that drug is not reabsorbed from the gastrointestinal (GI) tract.
