Question

Quizplus · Accepted Answer

The respiratory system plays a key role in maintaining acid-base homeostasis by eliminating carbon dioxide through breathing. Carbon dioxide is a weak acid, so removing it from the body helps to regulate the pH of bodily fluids. The urinary system also helps to regulate pH by filtering and excreting excess acid or base, but it is not the primary mechanism for eliminating carbon dioxide. Buffer systems and metabolically active cells also contribute to acid-base balance, but they do not directly eliminate carbon dioxide like the respiratory system does. Therefore, the best choice is A, the respiratory system.
