Fish gills exchange surfaces
WebAquatic arthropods generally possess some form of gills in which gas exchange takes place by diffusing through the exoskeleton.Others may breathe atmospheric air while remaining submerged, via breathing tubes or trapped air bubbles, though some aquatic insects may remain submerged indefinitely and respire using a plastron.A number of … WebThe folded surfaces of the gills provide a large surface area to ensure that the fish gets sufficient oxygen. Diffusion is a process in which material travels from regions of high concentration to low concentration until …
