Question

How do fish breathe?                                      

Answer 1

Fish breathe through gills that extract dissolved oxygen from the water they live in. As water flows over the thin, flat filaments of their gills, oxygen diffuses through the surface and into their bloodstream, while carbon dioxide is expelled. Fish need a constant flow of water over their gills to breathe, which is accomplished through swimming or by moving water over their gills through their mouths.

Answer 2

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. The gills are fairly large, with thousands of small blood vessels, which maximizes the amount of oxygen extracted.

Answer 3

Fish breathe through their gills. They extract oxygen from water as it passes over their gill filaments. The gills absorb oxygen and release carbon dioxide, enabling fish to respire and extract oxygen from their aquatic habitat.

Answer 4

Fish has specialized respiratory organs called gills that enable them to extract from water and release carbon dioxide.

1) Water Intake

2) Passing over the Gills

3) Gas Exchange

4) Oxygen Transport

5) Carbon Dioxide Removal

6) Carbon Dioxide Release

This process allow fish to continually extract oxygen from water and remove carbon dioxide, ensuring their respiratory needs are met. It's important to note that while fish brdeathe through gills, some species, like lungfish and certain catfish, have adaptations that allow them to breathe atmospheric air in addition to using their gills.

Answer 5

Fish breathe by taking in oxygen from the water around them. They do this through their gills, which are located behind the head and are covered by a flap of skin called the operculum. The gills extract oxygen from the water and then send it to the fish's bloodstream.

Answer 6

Fishes are aquatic animals that lack lungs like mammals. They therefore breathe through using a specialized and advance structure called gills. 

Gills are located on either sides of the fish head, protected by a bony plate called Operculum. Each gills have multiples of filaments covered with projections called Lamellae. They breathe by pumping water over their gills through opening and closing of their mouth or a specialized pumping system.

Another way they breathe is via they exchange of oxygen. Oxygen from the water diffuses into the bloodstreams through the gills filaments, simultaneously, carbon dioxide is removed from the blood stream via the gills into the surrounding water.

Answer 7

Fish breathe through gills, extracting oxygen from water. Humans, on the other hand, breathe air through their lungs. Attempting to breathe in a manner similar to fish is not feasible for humans, as our respiratory systems are adapted for air, not water.
