Expert Answer:

Liver plays a vital role in excretion of many substances. Liver helps in removal of ammonia from the body by synthesis of urea. The liver is well known to metabolize and excrete into bile many compounds and toxins, thus eliminating them usually from the body. These include steroid hormones, many antibiotics and metabolities of drugs. Dead, damaged and senescent red blood cells are digested by liver cells. Bilirubin is eliminated through bile.
