How are both kidneys and lungs related to waste removal in the human body?
Answer and explanation
Correct answer: Kidneys remove nitrogenous wastes and lungs remove carbon dioxide
Excretion removes metabolic wastes produced by normal cellular activity. The kidneys filter blood and eliminate nitrogenous wastes, especially urea, in urine. The lungs remove carbon dioxide and some water vapour produced during respiration. Thus both organs contribute to waste removal but handle different wastes, making option A correct; the other options incorrectly assign digestive, pumping, or bile-producing roles.
