Which relation between excretion and respiration is correct?
Answer and explanation
Correct answer: Wastes formed by respiration are removed by excretion or the respiratory system
The governing concept is removal of metabolic wastes. Cellular respiration produces carbon dioxide and water as end products. Carbon dioxide is transported to the lungs and removed during exhalation, while excess water may leave through the kidneys, skin or lungs. Excretion therefore helps maintain a stable internal environment by eliminating unwanted products. Option A is correct. The other choices confuse excretion with photosynthesis, digestion or a function limited to teeth.
