A Diagram Of A Fish Showing The Gills? Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that’s dissolved in the water. What should fish
Do Cartilaginous Fish Use Cocurrent Or Countercurrent Flow? Fish gills use a design called ‘countercurrent oxygen exchange’ to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes
How Fish Use Gill Rakers? While gill rakers have no role in gas exchange, the predominant function of gills, they do perform an equally important function for filter-feeding fish – food acquisition. These bony projections serve as a sieve to trap food particles. How many gill rakers does a fish have? Most fishes have three
