WebMost fish have a SA:V too poor for diffusion alone to be an effective method of getting oxygen, and their scaly outer covering means no gaseous exchange can happen at the surface. Gills are fish organs for gaseous exchange. Water … WebThis means the water flows through the gills in one direction, allowing for more efficient gas exchange than if the water had to go in and out the same way. This is important for fish becaus of the low oxygen concentration in …
WebApr 6, 2024 · Most fish exchange oxygen and carbon dioxide that's dissolved in water. Gills absorb oxygen, which is dissolved in water and releases co 2 (carbon dioxide). Gills usually consist of lamellae (plates), tissues that are like thin filaments (protein structures), which have highly folded surfaces in order to increase the overall surface area. WebThe alveoli are adapted to provide a very large surface area for gaseous exchange: small size - each alveolus is a small sphere about 300 μm in diameter, giving it a larger surface area to...
