Excretion
Excretion cleans up after respiration. Your lungs excrete carbon dioxide as you breathe out, your kidneys filter out nasties to produce urine, removing nitrogen waste from your body, and your skin sheds excess salt through sweat. ... All vertebrate animals produce nitrogen waste in one form or another.
Nitrogenous waste
The nitrogen compounds through which excess nitrogen is eliminated from organisms are called nitrogenous wastes or nitrogen wastes. They are ammonia, urea and uric acid. All of these substances are produced from protein metabolism.
