Water enters a fishes gill, but as the water flows across the gills, oxygen inside the water diffuses into the fishes blood stream. At the same time, carbon dioxide from the bloodstream diffuses out into the water

Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
Why are Fish able to breathe in water?
Because they Have Gills, and gills help them to breathe in the water. As water flows over the gills, a fine network of blood vessels can extract oxygen from the water, much like our lungs collect oxygen from the air when we breathe.
How do fish get oxygen from the water in which they live?
most fish get their air from the oxygen-saturated water, but certain breeds (like bettas) do well in water with a low amount of dissolved oxygen, because they have a special resperatory organ called the labyrinth that allows them to breathe at the waters surface- in fact, they inherently must do so... unless they want to go to fishie heaven :(
What do fish breathe with?
Fish have gills, as they swim water passes over the gills and extract oxygen from the water.
Were do fish get there air from?
Fish pass water over their 'gills' the gills extract oxygen from the water.
What is the respiratory organ of fish?
Human beings breathe using our lungs. Oxygen goes into our blood and carbon dioxide goes out of our blood and into our lungs. When we breathe out we get rid of it. These gasses dissolve in our blood. In water there is dissolved oxygen. Fish don't have lungs; they have specially developed organs called gills. As water flows over the gills oxygen is absorbed and carbon dioxide can come out of the fish's blood through the delicate membrane of the gills. Some fish are able to pump water over their gills, which means that they can lie on the bottom or stay still in the water. Other fish need to keep moving to pass fresh water over their gills.
What does gills help fish do?
Fish use gills to extract oxygen from the water passing over the gills.
Since fish live in water and dont breath air does that mean fish can live in space?
No. Fish don't breathe air, but they still breathe oxygen, and there's no oxygen in space. They need oxygen just as much as we do; they just aquire it differently. The oxygen-rich water flows over their gills, and membranes in their gills absorb the oxygen from it and replace it with carbon dioxide.

How do fish and sharks get oxygen?
They use their gills to extract the oxygen from the water flowing over them
How do aquatic animals breathe?
Shellfish have gills just like fish do. They suck water into their shell and pass it over their gills, then squirt it back out again. Sometimes, you can see clams squirting water out of their shells when you are digging them up out of the sand.
How do fish get oxygen they need?
fishes uses the oxygen resolved in water.
