How are gills adapted for diffusion

Web12 de nov. de 2009 · In a fish, oxygen moves from the surrounding water through the gills to the blood and finally the tissues. At each step, the oxygen level becomes lower -- … WebVentilating the gills. Cartilaginous fish do not have an operculum; They therefore have to maintain a steady stream of water over the filaments to make sure they do not stick; Maximising gas exchange. Countercurrent exchange system; This allows for maximum diffusion as parallel is limiting as you can never fully diffuse oxygen from the water.

The circulatory system consists of the heart, … WebMost fishes exchange dissolved oxygen and carbon dioxide in water using gills which lie behind and to the side of the mouth cavity. The circulatory system consists of the heart, arteries, capillaries, and veins. The heart pumps the blood to the gills to be re-oxygenated. From there, blood is distributed to the tissues and organs of the body. streets of rage cd https://sofiaxiv.com
