Human Gas Exchange
... Fish obtain the oxygen they need from the water around them. To do this they need a system that is far more efficient at extracting oxygen than other non-aquatic animals because of the small amount of oxygen available in water. For this purpose, fish have gills. The gills of a fish have a large surf ...
