Web2 de jan. de 2024 · Summary. Hopefully you have seen that gas exchange in fish and insects is quite different to gas exchange in humans, but the principles are the same: 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 … WebExplain how a fish is adapted for gas exchange? A fish had gills, made up of gill filaments containing lamellae, which provide a very large surface area for oxygen to diffuse out of the water as it moves over them. The blood vessels are in very close proximity to the lamellae, allowing a short diffusion pathway. A fish also utilises a ...
