Question

5. How do gills help a fish to breathe?​

Answer 1

Answer:

The oxygen-rich water goes inside the fish from its mouth and leaves through gills. While this water is passing by the gills, the capillaries inside it absorb the oxygen. In this way, a fish breathes inside water.

Explanation:

Answer 2

Answer:

In order to remove oxygen from the water, they rely on special organs called "gills." ... A fish breathes by taking water into its mouth and forcing it out through the gill passages. As water passes over the thin walls of the gills, dissolved oxygen moves into the blood and travels to the fish's cells.
