Web24 dec. 2011 · Gills and lungs are the main tissues that provide gas-exchanging surfaces for the respiratory function of most of the higher animals. Primarily fish has gills while amphibians, reptiles, birds, and mammals have lungs for respiration or gas exchange. WebFish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. bosch backblech pyrolysefest https://htctrust.com
