Fish are equipped with two sets of paired fins and several unpaired fins. Most fish exchange gases by using gills that are located on either side of the pharynx. Gills are made up of threadlike structures called filaments. Each filament contains a network of capillaries that allow a large surface area for the exchange of oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gill filaments. The blood in the capillaries flows in the opposite direction to the water, causing counter current exchange. They then push the oxygen-poor water out through openings in the sides of the pharynx. Some fishes, like sharks and lampreys, possess multiple gill openings. However, most fishes have a single gill opening on each side of the body. This opening is hidden beneath a protective bony cover called an operculum.
What else can I help you with?
Which gas is taken in when fish respire?
Fish are like humans in the way that they need oxygen. Fish breathe in dissolved oxygen and pass out carbon dioxide.
What reduces oxygen is ponds?
this is correct as the fish cause a bacteria to be generated as they are in a cramped environment. this bacteria saps oxygen from the fish, so the fish in the pond take more oxygen. then the plants take in more oxygen to try and compete so they can respire (not photosynthesize.
Which animal can respire in vacuum?
none, because you need oxygen to respire and a vacuum is the absence of matter and oxygen is matter
What gas given out when the fish respire?
Fish do not respire substance in the gas phase, the compound that "is given out" is Carbon Dioxide (in solution).
Which of these adaptations enables a fish to live underwater?
Gills are the adaptation that enables a fish to extract oxygen from water and release carbon dioxide. This allows fish to respire efficiently while living underwater.
What does both fish and waterweed do?
respire
How does fishes respire in water?
Fish respire in water through gas exchange in their gills.
Can fish breath in Coca Cola?
No, fish cannot breathe in Coca Cola as it does not contain the oxygen necessary for fish to respire. In fact, the carbonation and other chemicals in Coca Cola could harm or even kill the fish if they were submerged in it.
How much oxygen does forestry breath out?
*respire
When animals respire they take in what?
They take in oxygen
What is the means of respiration of clown fish?
All fish respire via the gills.
Why can our cells respire a aerobically for short time?
Our cells can respire aerobically for a short time because of the presence of oxygen in our muscles.
