Gills allow fish to breathe underwater because little people in the gills swallow the water and fart out oxygen for the fish. Gills allow fish to breathe underwater by breathing water in so they could let the bad water out. I think gills allow fish to breathe underwater by little men opening and closing the gills and taking in oxygen. Gills help fish breathe underwater because they are really wind up plastic fish that go underwater.
The real ones live in cans for cats to eat. Gills help fish breathe underwater because when fish hatch, SpongeBob and Patrick automatically appear and make them breathe.
Well, there are little scuba divers who are shrunk by a shrink ray. They go above and grab little bubbles of air and put them inside the fish over and over again. It got to all the fish, allowing their gills to help fish breathe. I think gills help the fish so they can have night vision. They can see in the dark. I think they can look out for predators. It helps you so you can go fishing in the dark and they can see your bait!
There is a special machine that controls the water. I think gills allow fish to breathe underwater because the gills could protect them to breathe in the ocean. I think because when they open their gills on both sides when the water goes in on one side and when it is in, it cleans the inside of the fish and takes all the bad germs out of the other side.
Fish can breathe underwater because their gills go intake and outtake and they have a little box inside them and then the water comes through the gills and water turns into oxygen. Gills allow fish to breathe underwater because they have little mouths on them that store oxygen made by the sharks. They open up and then they come up to take a big jump of air and then when they jump, they breathe and then the gills just go down.
When they swim up to the surface, they get air. But when they are underwater, the fish pumps up his lungs big so they can suck in air, not the water.
The gills helped because if you want the fish to jump, then you would want the fish to have gills. Also, there might be some bears. I think their gills work like this: They suck in water and it gets rid of the water, then the air goes to the lungs. Um, the lungs are there or something. Fish do absorb water through their skin and gills in a process called osmosis.
Osmosis is the flow of water across membranes from areas of low concentration of dissolved things solutes to areas of high concentration. It serves to equalize the concentrations in the two areas. In the case of freshwater fish, their blood and bodily fluids are much saltier than the water they swim in, so water will flow in through their gills.
The opposite is true for saltwater fish. As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
To stop the exploding fish phenomenon, their gills have special cells that selectively pump salt in, or out of their blood. In freshwater fish, the cells constantly pump salt in, and in saltwater fish, they constantly pump salt out. Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills.
Water goes in the mouth, across the gills and out through the opercula the bony covering protecting their gills. But gills and lungs are more similar than you might think. Both have really big surface areas which increases the amount of water or air that touches the gill or lung tissue, and so increases the amount of oxygen available. This means the capillaries come into close contact with the air or water outside, letting oxygen pass across the thin walls and into the blood.
At the same time, carbon dioxide, which is a waste product from our bodies, passes out. Hello, curious kids! Ask an adult to send your question to curiouskids theconversation.
