Skin has an important role in excretion in man . Skin releases sweat which contains harmful bacteria and many unnecessary  hormones with dusty particles. So Skin is important to clean our body by the process of excretion.
Lungs release Carbon dioxide ( CO2 ) which helps in the process of respiration and purifies blood.
Intestine helps in excretion of food digested in stomach and in duodenum.
