Which of the following dictate the respiratory surface of a fish?

Question

Quizplus · Accepted Answer

The respiratory surface of a fish is dictated by the size and number of gill filaments. These structures serve as the site of gas exchange, allowing for the diffusion of oxygen from the water into the fish's bloodstream and the removal of carbon dioxide from the bloodstream into the water. The volume of water over the lungs may have an effect on respiration, but it does not directly dictate the respiratory surface. The size of the operculum is important for creating water flow over the gill filaments, but it does not dictate the respiratory surface on its own. Therefore, choices A and C are incorrect.
