Utility of the Excretory System -

  • Animals accumulate ammonia, urea, uric acid, carbon dioxide, water and ions like Na+, K+, Cl–, phosphate, sulphate, etc., either by metabolic activities or by other means like excess ingestion. 
  • These substances have to be removed totally or partially                                            
  • Ammonia, urea and uric acid are the major forms of nitrogenous wastes excreted by the animals. 
  • The kidneys of animals have evolved to function in both excretion and the removal or conservation of water and salts.
  • Osmoconformers: Animals whose internal osmolarity changes in relation to their external environment.
  • Osmoregulators: Animals who can maintain their internal osmolarity at a particular level regardless of the external environment.
