Fish pull water in through their gills and filter it in the gill rakers. Then the water is forced through the gill filaments. These project out into the flow of the water, allowing the water to cross the lamellae. This results in what is called the "gas exchange". This is when oxygen is exchanged for carbon dioxide. The oxygen enters the blood stream directly when it moves over the capillary membrane. The carbon dioxide leaves the body with the flow of water out the operculum.

What else can I help you with?
How is a fish specialy adapted to exchange gases by diffusion?
XD
What is countercurrent breathing?
Countercurrent breathing is a method of gas exchange in which water flows in the opposite direction to blood flow. This enables a more efficient exchange of gases, such as oxygen and carbon dioxide, between the gills and blood in fish. It enhances the uptake of oxygen and removal of carbon dioxide from the blood.
How does shark exchange gases?
Like all fish- through their gills.
What is the breathing method of a bony fish?
Same as all the other fish. Water over gills, gills pull out needed gases and dispose of waste gases.
What does fish and young amphibians have that exchange gases with the water?
No it did not because i still did not get my answer i dont really like ask
How do fish take in gases?
Fish breath (take in and exchange gasses) by passing water through their gill membranes which do the same job as our lung membranes.
Where the exchange of gases is take place in the fish?
Across the alveoli and capillaries.
Compare how fish and lizards get oxygen into their bodies?
Fish use gills to extract oxygen from water, while lizards use lungs to extract oxygen from the air. Fish have specialized structures called gill filaments that allow for the exchange of oxygen and carbon dioxide in water, while lizards have a respiratory system composed of lungs and an expanded ribcage for breathing air.
What happenes to jaws and larynx during breathing and swallowing in fish?
The jaws and larynx during breathing and swallowing in fish, contracts. The jaws suck in, and the larynx contracts and closes temporarily while the breath is happening.
Two large organs in which the exchange of oxygen and carbon dioxide occurs?
The two large organs where the exchange of oxygen and carbon dioxide occurs are the lungs and the gills. In mammals, the lungs facilitate gas exchange between air and blood, while in aquatic animals like fish, gills perform this function by exchanging gases between water and blood.
What body parts do different animals use for breathing?
Generally the body parts used for breathing (exchanging gases with the atmosphere for respiration) are:lungs in most larger animals (mammals, reptile, birds)gills in aquatic animals (fish, amphibians, cephalopods)diffuse tracheal systems (insects)some animals use secondary methods of breathing as their gills or lungs are not sufficient for their needs (animals such as frogs and eels) they use their skin to supplement the gas exchange
Is my fish sleeping or dead?
To determine if your fish is sleeping or dead, observe its breathing and movement. If the fish is still breathing and shows some movement, it is likely sleeping. However, if there is no movement and the fish is not breathing, it may be dead.
