Why is it necessary to remove carbon dioxide from the body?
Answer and explanation
Correct answer: It is a waste product of cellular respiration
During cellular respiration, cells break down food molecules to release energy, and carbon dioxide is produced as a waste product, especially during aerobic respiration. If it accumulates, it can disturb the internal chemical balance and harm cells. It is transported in the blood to the lungs and removed during exhalation. Thus option A correctly states the reason; the other options confuse carbon dioxide with food, clotting factors, or digestive enzymes.
