Your fish uses countercurrent exchange of gases in their respiratory organ. Explain
the countercurrent exchange and where it occurs, and what advantage it provides for
your fish. Answer in a sentence format.
Expert Solution
Step 1
Most gas exchange during respiration in most of the animals happens by the counter current mechanism.
Animals could be aquatic or terrestrial. But whatever the medium it is in the direction of oxygen delivery and the organs to which it is delivered are in the opposite direction.
fish gills are designed to maximise the blood oxygen concentration by this arrangement.
