Professor PC Thomas Classes · Answer

(d) : In vertebrates, the lungs, liver and skin are referred as accessory excretory organs because besides the urinary system, these organs also participate in the removal of waste products from the body. The liver helps in the excretion of cholesterol, bile pigments (bilirubin and biliverdin), inactivated products of steroid hormones, some vitamins and many drugs. These are carried by the bile to the intestine and eliminated with the faeces. It has no role in secretion of urine.
