Question

how do fishes breath ?​

Answer 1

Answer:

How do fish breathe? ... With most—but not all—fish, the gills do the same thing. Fish take water into their mouth, passing the gills just behind its head on each side. Dissolved oxygen is absorbed from—and carbon dioxide released to—the water, which is then dispelled.

Answer 2

• The gills do the same function in most fish, but not all.
• Water enters the mouth of a fish by flowing via the gills on each side of its head.
• The water absorbs dissolved oxygen and releases carbon dioxide, both of which are eventually ejected.
• The gills are quite big, with hundreds of tiny blood channels, allowing them to extract the most oxygen.
• Fish, on the other hand, have a considerably harder time "breathing" since the amount of oxygen in the air is much higher than in the water.
