Excretion is the process of removing waste products from metabolic processes in organisms, involving specialized organs like kidneys, lungs, liver, and skin. It is crucial for eliminating toxic substances, maintaining internal balance, and regulating body temperature and water levels. The kidney, as a key organ in excretion, utilizes nephrons to filter blood and produce urine through ultra-filtration and selective re-absorption.
