EXCRETORY ORGANS:
in mammals-kidney.
liver also take part in excretion, as it allows urea bio-synthesis in it.
in fresh water mollusks-organs of bojanus.
in star fishes-excretory pigments.
in many invertebrates and vertebrates it is nephredia.
uricotelic- uric acid is excreted-in animals which have to conserve water.
ureotelic-urea is excreted in mammals and in some other animals.

Technically, the intestine is not an excretory organ.

1. The lungs excrete carbon dioxide and water.
2. Sweat glands excrete water, salt, and traces of urea.
3. Large intestine excretes water and other wastes including undigested food. This constitutes feces.
4. Kidneys excrete water, urea, and salts. This is called urine.

1) Lungs - carbon dioxide
2) Kidneys and skin - Nitrogenous waste products: mainly urea ( from deamination of proteins ), creatinine ( from muscle breakdown ) and uric acid ( from breakdown of nuclear materials )
3) kidneys, skin and lungs - excess water
4) liver - Bile pigments ( from haemoglobin breakdown )
