How fish are adapted for gas exchange
Web2 jan. 2024 · Gas exchange surfaces are adapted to maintain a high rate of diffusion: they have a large surface area, are thin, and are ventilated to maintain high concentration gradients of oxygen and carbon dioxide. Ventilation happens due to changing volume and pressure (in the buccal cavity in fish). Webof fish. The disease causes the lamellae to become thicker and to fuse together. AGD reduces the efficiency of gas exchange in fish.
