Answer 1

One metabolises compounds, ie. conversion of Codeine to Morphine, or hormone synthesis such as Cholesterol to Progesterone (liver) and the other is a filtration system for waste products ie. Urea that would otherwise build up to toxic levels within the bloodstream (kidneys). Essentially, your liver breaks compounds down, to be removed from the body via the kidneys.
